How to Convert Fractions to Percent

Apart from the obvious use of a calculator to convert a fraction to percent, there are three methods you can use. Let us take you through them.

Multiply top by 100

Let’s show you in an example:

What is 6/8 as a percent?

Multiply the top number in the fraction by 100.

Then divide that number by the bottom number.

Change the fraction to ?/100 form

Example:

Convert ¾ to a percent.

Find a number you can multiply the bottom of the fraction by to get 100.

Multiply both top and bottom of the fraction by that number.

Write down just the top number with the "%" sign.

Use proportions to convert the fraction to percent

As a percent is a ratio (parts per 100) we can use proportions to do the conversion.

Here’s the formula:

Example: convert 5/16 to percent.

You multiply across the known corner:

and divide by the third number:

Percent = (5 x 100) / 16 = 500 / 16 = 31.25%
