this website get really confusing sometimes

I know it really does but you just need to get to use it

Can you have a decimal point for the dominator?

Yes, it's possible to have a decimal in the denominator, but a fraction like this isn't fully simplified. To simplify, we move the decimal point the same number of places to the right in numerator and denominator to get rid of the decimals, then we reduce as usual from there. For example, 2.4/0.18 is equivalent to 240/18, which then reduces to the improper fraction 40/3 or the mixed number 13 and 1/3.

i'm having hard time with this.

Hi Nina! This is quite simple once you understand it. So basically lets say the percentage is 30% Converting it to decimals would be 0.30, or 0.3 if you simplify it because as you should know the second digit wafter the decimal point is the hundreths place. For fractions it would be 30/100, or 3/10 simplified because 30% of 100 would be 30 parts of 100! Hope this helps! You can always comment any more questions you have!

in the second practice how can you convert a mixed number to a percent

You change the mixed number into an improper fraction. Then, multiply by 100 5 1/4 = 21/4 21/4 * 100/1 = 2100/4 = 525% Hope this helps.

Why didn't 175% not need a decimal before the 7 and after the 1.

7/4 is the same as 175/100 (4x25 = 100) & (7x25 = 175). As we know *per cent* means *per hundred*. Since we converted 7/4 to hundredths, we simply need to remove the /100 and add the percent sign (%). If you were to write it with the decimal point like this 1.75%, and then convert back to a fraction, the fraction would be 7/400.

Review writing percents as fractions and fractions as percents. Then, try some practice problems.

Writing percents as fractions

Percent means 'per hundred.' So, we can replace a percent sign with 'per hundred.'

Example

Let's write

15 %

as a fraction.

15 % = 15 per hundred = \frac{15}{100}

Writing fractions as percents

Percent means 'per hundred.' So, we want to create an equivalent fraction with

100

as the denominator.

Example

Let's write

\frac{4}{5}

as a percent.

The key here is to turn

\frac{4}{5}

to a fraction with a denominator of

100

. To do this, we need to know what times

5

gives us

100

$5 \times 20 = 100$ ‍

Now we're ready to convert

\frac{4}{5}

to a percent:

\frac{4}{5} = \frac{4 \times 20}{5 \times 20} = \frac{80}{100}

\frac{80}{100} = 80 per hundred = 80 %

Practice

Problem 2A

Convert $\frac{1}{10}$ ‍ to a percent.

to find the simplest fraction you have to dive the numerator and denominator as much as you can until you cannot find a common factor
