Question

Express the ratio as a fraction in simplest form. 15:45 2/3 3/9 1/3 5/16

Answer 1

3/9

Explanation:

15/45

divide both sides by a factor of each number; I'll be using 5.

3/9

It didn't have to be 5, I could have used 3, but in that case It wouldn't have been it's simplest form and I would have to divide again by another factor.
