Rewriting decimals as fractions: 0.15
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction. Created by Sal Khan.

- what if i have a number in the thousands place also?(103 votes)
- It's just the same as the tenths and hundredths..you would do the problem the same(155 votes)
- what? i have no clue what he means! pls help me(13 votes)
- Let's say you have the decimal 0.66 and you want to make it a fraction. Well, how do you say it? You say zero point six six, or sixty six hundredths, which is:
66/100 . . .
- what if the number was bigger than the denominator(5 votes)
- You make the fraction a mixed number. For example: 24/9. 9 goes into 24 2 times right? So that's the whole number next to the fraction. 6 is left because 9 X 2=18 and 18 is 6 away from 24. Now 6 is the numerator. So now the answer is 2 6/9. Understand?(12 votes)
- I am so confused. Can someone please explain this to me?🤔(5 votes)
- Okay. If you are confused, let me tell you more.
If you have a fraction that has the numbers 10, 100,* or *1,000 in the denominator, it also has a fraction form:
.0 = tenths
.00 = hundredths
.000 = thousandths
Lets say your numerator is 19.*
The full fraction is *19/100.*
This would be listed as *0.19 because
.00 = your 100th (19/100) so nineteen would take the place of the zeros:
If this still doesn't make sense, say the fraction aloud: nineteen hundredths.* That would be the same as if you said: *0.19 aloud.(10 votes)
- How do you divide a neverending decimal?(6 votes)
- There is a way but as you say, a never ending decimal has no end so you can't get a answer that is not never ending when dividing.
e.g pi divide ? would equal 0.?(10 votes)
- what if i have a number in the tenths and tens place would that be the same thing(6 votes)
- No. For example 32.5
The 3 would be in the tens place and the 5 would be in the tenths place. The tenths is used for number after the decimal point. Then, if we have 32.51, 5 would be the tenths place and 1 would be the hundredths place etc.(5 votes)
- How can you convert a repeating decimal into a percent?(1 vote)
- To convert a decimal into a percent all you have to do is multiply by 100.
0.55 * 100 = 55 Percent(4 votes)
- I have a question how to convert ( -0.38 the 8 is repeating) into a fraction ? THX(2 votes)
- Like what if the number is -0.5 with the line over the top(3 votes)
- -0.5 repeated can be written as -5/9 in fraction form.(4 votes)
- what if i have a number in the thousands place also?(3 votes)
- I'm assuming you mean thousandths place (a decimal place value).
Let's try: 0.245
Since the right most digit is in the thousandths place, the denominator = 1000
The fractions becomes: 245/1000
Then reduce the fraction. We have a common factor of 5. Divide both numerator & denominator by 5. The new fraction = 49/200
Hope this helps.(2 votes)
Let's see if we can write 0.15 as a fraction. So the important thing here is to look at what place these digits are in. So this 1 right over here, this is in the tenths place, so you could view that as 1 times 1/10. This 5 right over here is in the hundredths place, so you could view that as 5 times 1/100. So if I were to rewrite this, I can rewrite this as the sum of-- this 1 represents 1 times 1/10, so that would literally be 1/10 plus-- and this 5 represents 5 times 1/100, so it would be plus 5/100. And if we want to add them up, we want to find a common denominator. The common denominator is 100. Both 10 and-- the least common multiple. 100 is a multiple of both 10 and 100. So we can rewrite this as something over 100 plus something over 100. This isn't going to change. This was already 5/100. If we multiply the denominator here by 10-- that's what we did; we multiplied it by 10-- then we're going to have to multiply this numerator by 10. And so this is the same thing as 10/100. And now we're ready to add. This is the same thing as-- 10 plus 5 is 15/100. And you could have done that a little bit quicker just by inspecting this. You would say, look, my smallest place right over here is in the hundredths place. Instead of calling this 1/10, I could call this literally 10/100. Or I could say this whole thing is 15/100. And now if I want to reduce this to lowest terms, we can-- let's see, both the numerator and the denominator are divisible by 5. So let's divide them both by 5. And so the numerator, 15 divided by 5, is 3. The denominator, 100 divided by 5, is 20. And that's about as simplified as we can get.
