Question

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

Answer 1

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,

`12/4` = 3

and

`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.
