How can you make 25 over 75 have a denomenator of 100?

Answer 1

Create a ratio.

25/75 = X/100

Multiply both sides by 100 to get 2500/75 = X

Reduced, 2500/75 = 33.3333... = X

It's a little messy to write it as "33 1/3" if you need it as a numerator. However, that is the answer.

You can also write it as a continuing decimal in the numerator. It would be written 33.3 with a bar over the last 3.

Another way to do this:

25/75 = .33333...

".3333...." is a fraction with a denominator of 1. Multiply this fraction by 100/100 to get "33.333.../100"
