How do you convert a fraction into a percentage?

⓵ You need to use what we call a cross product. This method is also also known as cross multiplication. Let me show you an example :

Say you had 17/20 in a test and you really want to know what percentage that represents.

17 / 20 = × / 100

I then like to change the writing form to visual everything better :

17 → 20
× → 100

And then I transform this proportion into an equation to solve it :

(17 x 100) ÷ 20 = ×



1700 ÷ 20 = ×



85 = ×


So 17/20 turns out to be equal to 85/100 which is 85%!

I hope this helped, if there’s anything just let me know! ☻

Divide the denominator from the numerator.

For example:

1/8 is the same as 1÷8

Then do long division:
_____
8) 1

You will get 0.125
