## Enter proportion values below:

 ---------- =<≤>≥ ----------

 x 8
 =
 4 32

##### 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 Numerator 1 we get:

 Numerator 1  = Denominator 1 * Numerator 2 Denominator 2

##### Evaluate and simplfy

 x  = 8 * 4 32

 x  = 32 32

x = 1

#### You have 2 free calculationss remaining

x = 1
