Decimal to simplified fraction
Here's an example of how we convert a decimal to a simplified fraction. Over time this will become second nature to you.
Discussion and questions for this video
 Write 2.75 as a simplified fraction.
 So once you get some practice here.
 You're going to find it pretty straightforward to do.
 But we're really going to think through it and get the
 intuition for why this makes sense.
 So if we were to write this down, the 2, that literally
 just represents two 1's, I'll just write it down like that.
 Then we have the 7 in another color.
 We have a 7 one place to the right of the decimal.
 It's in the tenths place, with a THS at the end.
 So it literally represents 7 over 10.
 And then finally, we have the 5 in the hundredths place, so
 it represents 5 over 100.
 Now, if I want to write this as a simplified fraction, or
 really as a mixed number, I have to merge these fraction
 parts right here.
 And to add two fractions, you have to have a common
 denominator.
 And to figure out the common denominator, you just have to
 think about the least common multiple of 10 and 100.
 And that's 100.
 100 is divisible by both 100 and 10.
 So let's get this 10 to be 100.
 So we can do that by multiplying it by 10.
 So when you multiply something by 10, you add a zero
 at the end of it.
 But you can't just do that to the denominator.
 We also have to do that to the numerator.
 So we multiplied the denominator by 10.
 Let's also multiply the numerator by 10.
 7 times 10 is 70, or 70 over 100.
 It's the exact same thing as 7/10.
 Now we can add these two.
 What is 70 plus 5?
 70 plus 5 is 75.
 And our denominator is 100, so this can be
 rewritten as 2 and 75/100.
 And we saw that in the last video, you would read this as
 two and seventyfive hundredths.
 Now we aren't in a completely simplified fraction yet
 because 75 and 100 have common factors.
 And the largest number that goes into both, if you're
 familiar with quarters, is 25.
 Three quarters is $0.75, four quarters is 100 cents, or four
 quarters is $1.00.
 So you divide both of them by 25.
 So 75 divided by 25 is 3, and 100 divided by 25 is 4.
 So as a simplified mixed number, this
 becomes 2 and 3/4.
 And after you do a lot of practice here, and you just
 see a lot of numbers like this, it will be almost second
 nature for you to say, oh, 2.75 is the same thing as 2
 and 75/100, is the same thing as 2 and 3/4.

how do you convert a fraction into a decimal?
You should divide fraction's numerator by denominator.
For example:
3/4 = 3 : 4 = 0,75
Sal made few videos about it, here is one:
https://www.khanacademy.org/math/arithmetic/decimals/decimal_to_fraction/v/convertingfractionstodecimals
For example:
3/4 = 3 : 4 = 0,75
Sal made few videos about it, here is one:
https://www.khanacademy.org/math/arithmetic/decimals/decimal_to_fraction/v/convertingfractionstodecimals
example0.789=789/1000.The digits after the decimal points will be divided by the number of zeroes.but we have to add 1 before the zeroes.
so if you have 3/5 you can divide 5 by 100 which is equal to 20 and then multiply 20 and 3 which is equal to 60 so the answer is 0.60
Divide the numerator by the denominator.
For example 1/4 = .25
For example 1/4 = .25
We'll I suggest any one reading this listen carefully!
You have to divide the denominator by the numerator like this:
3/4
4 divided by 3 = 0.75
You have to divide the denominator by the numerator like this:
3/4
4 divided by 3 = 0.75
for example, 4/10 or 4/100
4/0 turns into 0.4 because denominator is 10. 4/100 is 0.04 because denominator is 100.
4/0 turns into 0.4 because denominator is 10. 4/100 is 0.04 because denominator is 100.
You could just divide the 2 numbers together and get a decimal.
Let me give you an example...55.First, do 55/100. Simplify it to11/20 Thats how you do it. Its mostly per 100 (/100)
It is simple. The denominator is the dividend, and the numerator is the divisor!
You can either divide the numerator by the denominator or multiply the denominator so it is equal to a power of ten. Then you can multiply the numerator by the same amount.
Divided the numerator into the denominator.

divide by 100 or by10

How do I write a mixed number as a percent
First step, get the denominator to 100
17 1/5 becomes 17 5/25 becomes 17 20/100
Second step, write the mixed number as a decimal number
17 20/100 becomes 17.20
Third Step, move the decimal point two digits right then add a "%".
17.20 becomes 1720%
17 1/5 becomes 17 5/25 becomes 17 20/100
Second step, write the mixed number as a decimal number
17 20/100 becomes 17.20
Third Step, move the decimal point two digits right then add a "%".
17.20 becomes 1720%
This is an example. is there is an improper fraction like 15/7 divided 15 by 7. You will get 2 and 1/7. Hope this helped :)
ya exactly
it like kurkure
it like kurkure
Ew no they NASTY
What kind of question is that? Cade smith?
you change the mixed number/fraction into a improper fraction
then, you divide the numerator by the denominator
like this 10/7..............10 divided by 7
then, you divide the numerator by the denominator
like this 10/7..............10 divided by 7
how do you change a decimal to a fraction when it has 3 numbers behind the decimal?
Hey Olivia!
When changing a decimal to a fraction when it has 3 numbers behind the decimal, you may try to do the following:
Suppose that your decimal is 1.234. You may want to associate it with a fraction involving someone associated to the "family of tens". Who could divide 1234 (the whole number without decimals) in order to bring the decimal so far?
Since we have three decimals, the answer would be someone in the family of tens with three zeros  Which is the number 1000, getting us to the fraction 1234/1000  Leaving us with the simple job to simplify it.
If you think of the number 123.4, the process is the same: Just think about who in the family of tens would bring the decimal that far. Since there is 1 decimal value, we would think about someone in the family of tens with a single zero: 10 itself! The fraction would be 1234/10 in this case.

if it is 1.234000 do not worry because just ignore the zeroes and do like Arthur said.
How do you add Decimals and fractions?
convert the decimal to a fraction or vice versa, and then proceed as the form dictates
You either change the decimal to a fraction or the fraction to a decimal.
For example say we need to add .75 and 1/2. I would change 1/2 to a decimal which is .5. Then I
add them together and get the answer. Sometimes doing the fraction way is harder because you have to simplify and get the common denominator.
Hope this helped!

You would need both terms (numbers) to be the same, either fractions or decimals.
For example, say we need to add 1/2 + 0.75. There are two ways to work this problem.
1. Convert 1/2 to a decimal (0.5) and add it to 0.75: 0.5 + 0.75 = *0.8*. †
2. Convert 0.75 to a fraction (3/4) and add it to 1/2: 3/4 + 1/2 = 3/4 + 2/4 = *5/4*.
† Correction: 0.75 + 0.5 = *1.25*.

What is a mixed number? I forgot. :/
A mixed number is a whole number, such as 3, 3, or 1, connected to a fraction. An example of a mixed number is 3 1/2.

How do you get a black hole badge
They are nearimpossible. Good luck!
Out of the 3 black hole badges, the "easiest" one to get is Tesla, which you get for earning 10 million energy points. It's not very clear how to get the other two (Artemis & Atlas). Good luck!
so when i make a mixed number to improper fraction iin dividing fractons i have to flip it around again?
I don't think so. 1 3/4 will turn into 7/4.
.126 x 1 1/9 =?
The answer would be 0.14, or 7/50, since .126 can be written as 63/500, then if you cross multiply it with 11.9, you get 7/50.
my answer is 0.14
7/50=0.14

How would I go about approximating .68 inch to the nearest eighth of an inch?
First you would need to find which 8ths it falls between.
4/8 = 0.5
5/8 = 0.625
6/8 = 0.75
So we will be rounding to either 5/8 or 6/8 and need to decide which one is closer.
.68  .625 = .055
.75  .68 = 0.07
0.055 < 0.07 so we round to 5/8.
The other way to do it would be to first multiply 0.68 * 8 to get 5.44. This rounds down to 5 then divide by 8 so again we get 5/8.
4/8 = 0.5
5/8 = 0.625
6/8 = 0.75
So we will be rounding to either 5/8 or 6/8 and need to decide which one is closer.
.68  .625 = .055
.75  .68 = 0.07
0.055 < 0.07 so we round to 5/8.
The other way to do it would be to first multiply 0.68 * 8 to get 5.44. This rounds down to 5 then divide by 8 so again we get 5/8.
Yes, that is true.
hi and thks u
can anybody please tell me how to simplify a fraction please. :)
Well, to simplify a fraction first you have to make sure none of the numbers are prime. Prime means that the number can't be divided by anything to get an integer (whole number). If the number in the numerator or denominator is prime then the fraction is simplified. If the numbers are not prime then you should find the greatest common factor. That means you have to find the largest number that both the numerator and denominator can be divided by.
If there is no number that both the numerator and denominator can be divided by then the fraction is already simplified. Please note that both numbers being divisible by 1 does not mean that you can simplify the fraction. Any number divided by 1 is itself. If your fraction can be simplified then divide both numbers by that number. If you can find another common number that both the numerator and denominator can be divided by then simplify. This shouldn't happen if you find the greatest common factor. Although sometimes using lower numbers is easier. Keep simplifying and checking to see if any of your numbers are prime or do not have a common factor.
At this point your fraction is simplified. :) Feel free to reply if you have any questions. Sorry for the bad paragraph formatting, the reply started out as a big blob of text.

Can you make a video on how to simplify fractions?
isn’t 2.75 = 275/100?
Yes, 2.75 = 275/100, but we can simplify that. It simplifies into 2 75/100 which simplifies down again to 2 3/4.
Yes it is 275/100, splitting it into it's parts to verify it to help you understand it is 2 + 7/10 + 5/100, making all the denominators the same turns that into 200/100 + 70/100 + 5/100 = 275/100
How do i write a fraction as a percent if the numerator is not divisible by the denominator (e.g. 5/7)?
5/7 = 0.7142857143 and so on
*100 = 71.42857143
you would have to round it as you wish. that's why it's better kept as a fraction for accuracy.
*100 = 71.42857143

You do it as a division. 5 divided by 7. You need to be able to do division involving decimals. See https://www.khanacademy.org/math/ccsixthgrademath/cc6tharithmeticoperations/cc6thdivision/v/dividingcompletelytogetdecimalanswer
Just divide 5 by 7 by adding .0 to 5 to become 5.0 divided by 7 then divide.The answer will be 0.713.Then move the decimal point twice to make it between 1 and 3 so the answer is 71.3%
how do you convert 22/32 into decimals
You have to divide 22 by 32.
22 divided by 32, after computing the long division, equals 0.6875.
the area of a square Is 144ft square . what is the length of one of the sides of the square?
To find the length of the side of a square, you find the *square root* of the total area. In this case, the length would be *12 ft*, since the square root of *144* is *12*.
i just don't get how you can change a decimal into a fraction it has been confusing me for a while so do you think anyone could help me understand it better?
decimals into fractions: use the place value of the decimal number
.75 means 75 hundredths, so write it 75/100, then reduce (divide) 75 and 100 both by 25, to get 3/4. (75/25=3, 100/25=4)

how to convert a percent(%) as an improper fraction
To convert a percent to an improper fraction, you need a percent with a value that is greater than 100 percent. Let's say that you had a percent such as 134%. You can convert this percent into 1 34/100 because you have one whole 100% and 34% left over.

Hi How do you convert a fraction to a decimal i dont really get it
That is actually very simple to do. Let me give you an example:
What is the decimal form of 1/2?
All you do is treat the bar as a division bar and voila!
So 1/2 would be 1 divided by 2, which is 0.5.

HELP!! How do you do percent times percent? It is so confusing...
it's just like regular multiplication, but you have to convert the percents to decimals first and remember the rules about how multiplying decimals work. so 50% time 60% is .5 times .6 which equals .3. convert that back into a percent, you get 30%.
You just turn it into decimals or fractions then you multiply it and then turn it into a percent.
If 46% = 30 sheets of paper, how do I find out how many sheets = 54%
This will be a two step problem.
The first step, you will need to figure out the total number of sheets of paper. Put the 46% over 100% and the 30 sheets of paper over X, and set them equal to each other.
46/100= 30/X
Cross multiply and you get
46X=3000
Next divide 3000 by 46 to get the total sheets of paper.
X=65.22 sheets of paper.
Now, you have to figure out 54% of that. Simply multiply .56 by 65.22.
The answer is 36.5232 or ~36 sheets of paper

If i were to add fractions to a decimal then multiply it by a negative number what would i do
You would want to reduce as far as possible and then Solve. Do you know what an improper fraction is?
I was a little lost but after watching the video again i got it
Er, today at my school, my teacher asked what was 0.23 in fraction and no one knew it, please help so i tell my teacher.
You should first say the name of the decimal number. Since the final digit is in the hundredths place, you would call it twentythree hundredths. There is a fraction with the same name.
if you have a fraction that is like lets say 25/100 it is going to be 25 percent
it is 1/4 in fraction.
Why do we have decimals and fractions and percents?
Why don't we just have one like fractions and not have any other?
Why don't we just have one like fractions and not have any other?
There are many contexts in which numbers are used. Each type of number is ideal at times when others are not. We have variety to maintain flexibility.

move the decimal 2 places to the right
so you can just add the fraction by making a picture.
yes. it will help u visualise it
I think so. But their might be a easy way too.
yes
yes, if you do it like he showed then it would make it alot easier!!!
can you make more examples?
okay so lets say we had 10/20 to make it smaller halve it once you will automatticly have 5/10 but if you had 60/70 you would have to halve it a couple of times! that was the fractions! if we had 10/50 just take the dit away and add the decimal point its that easy! that was the decimal!
Can this way be used for all problems like that?
Thanks!
yes it can be even if you have over thousands of numbers even if YOU cant i can
Sorry if you have 4 numbers..
Yes if you have 3 numbers in the decimal then it will be totally different.
definitely... i think.
I believe so.
I have a question... when you make 7/10 into a common denominator...do you just add a zero to the end to make it the same?
:)
demoniter is hard but simple and what they said is the most simple ones so im not going to put doiwn the hard ways soz =(
:) thank you so much!
7 divided by 10? no, its written like this:
7

OK thank you!
Putting the zeros to the end of the numerator and denominator is the same as multiplying by 10/10 because 7x10=70 and 10x10=100 .
Multiplying by 10/10 is the same as multiplying by 1, just to make the denominator the same.

Hey guys, I just figured out an amazing shortcut to converting decimals to fractions. If you already know how to read decimals, it should be easy. By that, I don't mean, (four point three two one). I mean, (four and three hundred twentyone thousandths). If you don't know how to read decimals, check out this link:
http://www.mathgoodies.com/lessons/decimals/read_write.html
Okay, back on topic. An easy way is to just read the decimal out loud, then write down the fraction just like it sounds. Here's an example:
Write 4.93 as a simplified fraction.
First, read it out loud to yourself.
_Four and ninetythree hundredths._
Now, write it down just like you read it.
4 93

100
Last but not least, simplify the fraction if necessary.
Pretty cool shortcut, huh?

For this question I would first convert the fraction part to a decimal. 1/2 = 0.5 You can do 1.0 ÷ 2 by long division to get this. Then add the whole number part. 19 + 0.5 = 19.5
does the first number of the decimal always stay the same when u are turning it to a mixed number
The denominator stays the same unless simplifiable.
So at around 1:58 he says "they have common factors" what does he mean by that exactly?
he had 75/100 , so in this case 25 is a factor of both numbers. ie 75 = 25 x 3 and 100 =25X4
in general factors of a number are numbers that can be used to build up that number , ultimately you get to prime factors where the number cant be broken down any more. There are videos on this topic if you didn't manage to get to them.

What happens if there is a thousandth? For example: 8.452? How would you write that as a fraction?
It would be 8 452/1000. Then you just have to reduce the fraction.
What if you have something like 6/51 how would you convert that into a decimal? I'm just not understanding the process I guess. I've read the other comments and tried at school, but I can't get it in my head. I'm finishing 8th grade if that matters.
Hi Jake. Finishing 8th grade is very important. This means you need a quick, easy way of understanding how to convert fractions to decimals. Decimal are going to be very important in Algebra I and II.
So here is a quick and easy way to find the decimal: construct a division problem. Take the numerator (6, in this case) and put it inside the division sign.
*
) 6*
Good? now put a decimal point after the whole number. So it should look like this:
*
) 6.*
Now put the denominator (51) on the outside:

51) 6.
Okay? Now put the decimal directly above, in the product area.
* .
51) 6.*
Now complete the problem. You should have one number in front of the decimal point (because 6 is only one digit) and the rest should be behind the decimal point.
The answer will be 0.1176470588 (etc.) Round it and you'll get approximately 0.118.
Hope this helps. If you need more help, just say so and I can give a lot more examples.

how come I just lost all my achievements for watching videos?!?
Is it just me or did it happen to anyone else?

what makes you arrived at three all over four?
75 / 100 = (3 x 25) / (4 x 25) Since 25/25 = 1, (25 is GCF of 75 and 100), 75 out of 100 is the same as 3 out of 4.
Is there an easy way to figure out how to simplify 5754/10,000?
First, look at the 2 numbers. You have 5754 and 10,000. You'd have to figure out what the GCF of both numbers are.. or just see.. 2 goes into both numbers, so divide them both by 2, and so on and so on.
whats the answer to 7 over 26
How do you change a fraction into a decimal and vise versa?
O.17 as a fraction
Well, you start out by finding out how many numbers are behind the decimal.
17 has 2 numbers. So if it had 1 number (lets call it ?) then it would be ?/10, but since there are 2 numbers it is 17/100. Since 17/100 isn't divisible by anything the answer is 17/100!

I need to turn 1/6 to a decimal. The answer is supposed to be .1666, I don't understand how they got the 1?
Hey Nicole!
Not sure how you are getting that answer... The easiest way to do it is to plug it into a calculator but if you go ahead and divide it out you should get the same answer. How were you doing the problem?

how do you order fractions
first you convert them into decimals.Next or der the decimals from lesat to greatest then convert them back into a fraction. A good smartthinking tip always label what each fraction equals to the decimal. for example 1/4=0.25 thats a good tip so its less work. :)
Can anyone explain how to do the cut and copy excersies I dont understand them at all.. for example this question..
The starting block below is 116 units long. Use the tools to the right to convert the starting block into both of the goal blocks that are 23 units long and 56 units long. You can see your progress as the current blocks.
Cutting the starting block into x pieces is the same as dividing it by x.
We want to cut the starting block into a piece that can be copied into both goal block 1 and goal block 2.
The least common denominator of 3 and 6 (the denominators of the goal blocks) is 6. Therefore you can copy a block 16 units long to make both goal blocks.
To find the number of slices to cut the starting block into we solve for s in the following equation:
116÷s=16
116=16s
116⋅6=s
s=7
We now have a resulting block that is 16 units long. Now we simply divide our goal blocks by this value to see how many times we need to copy the resulting block.
c1=23÷16=23⋅6=4
c2=56÷16=56⋅6=5
I really dont get this explanation at all.

how do you convert an infinite decimal into a fraction
If the decimal does not have a repeating pattern, then the number is irrational and cannot be converted into a fraction.
However, if there is a pattern, then the way I do it is to write the repeating pattern in the numerator, then count up the digits in the numerator and write that number of nines in the denominator then simplify.
Example:
.102102102... = 102 / 999 = 34 / 333
However, if there is a pattern, then the way I do it is to write the repeating pattern in the numerator, then count up the digits in the numerator and write that number of nines in the denominator then simplify.
Example:
.102102102... = 102 / 999 = 34 / 333
Why cant i just write 75/100 in the first place because .75 is just 75/100
im not grasping that well :(

Hey Rosalyn!
Idk if the other guy already answered your question or not, but I thought I would go ahead and post an answer here in case it can help you or someone else.
1/4 is equal to 0.25, and 3/4 is equal to 0.75, so 0.4 would be greater than 1/4 (or 0.25) and also between 1/4 (0.25) and 3/4 (0.75).
0.76 is greater than 3/4 or 0.75.
I'll also write it out a different way just so you can see it. Here is the first number, 0.4.
1/4 < 0.4 < 3/4
The second number, 0.76:
1/4 < 3/4 < .76
Hope this helped and didn't just make things more confusing. :) let me know if I can help clarify anything.

Hmm,..I'll post a tutorial on my website right now! Maybe I could be of some use.
"2:01" So we're supposed to find the largest number that fits into both?
Oh! I get it. Thanks!
your supposed to find the smallest number that fits into both i am pretty sure. basically he was simplifying it and i, for some reason, forgot how to simplify. i hope i could help a little!
how do you find out how to divide decimals?
The only way I remember is turn them into fractions and do this:
a/b divided by c/d. Invert c and d and change it multiplication.
a/b multiplied by d/c. Multiply numerator and denominator. Then change back to decimals.
Hope this helped! :D

wat if its was like there was giomg on and on do we have to put a infinity bar yes or noo like we leave it like that?
How do it from the fraction to the decimal not from decimal to fraction
If it is a fraction, e.g. 2/5, try to make the denominator into multiples of 10 (10,100,1000) so for 2/5 it becomes 4/10 then take the numerator and move the decimal point to the left once for each 0 after the 1 ( if 10 then once, if 100 then twice etc..) so in this case move it once. Therefore 2/5 = .4
can you please go slower ????
