# 3.75/18.75 = 5/m

## Enter proportion values below:

 ---------- =<≤>≥ ----------

## You entered the following equivalent proportions:

 3.75 18.75
 =
 5 m

## Define the proportion formula:

If 2 proportions are equal:
we can cross multiply to get:

 Numerator 1 Denominator 1
 =
 Numerator 2 Denominator 2

Numerator 1 * Denominator 2 = Denominator 1 * Numerator 2

## Solving for Denominator 2 we get:

 Denominator 2  = Denominator 1 * Numerator 2 Numerator 1

## Evaluate and simplfy

 m  = 18.75 * 5 3.75

 m  = 93.75 3.75

m = 25
