# How do you simplify to tell whether the ratios 4/5, 12/15 form a proportion?

May 3, 2018

These fractions are equivalent because they can both be divided by the same numbers.

#### Explanation:

First, we must find a number that can be divided into both the numerator and the denominator in order to get the same answer,

$\frac{12}{4}$ = 3

and

$\frac{15}{3}$ = 3

This means that 4 * 3 = 12 and 5*3 = 15
as a result, these fractions are equivalent because they can both be multiplied by the same number to get the result. In this case, 3.
