Steps for finding the solution

We have 12/65 = 15/x

Cross multiplying the ratios, gives

12x = 65 × 15

Divide both sides by 12, which is the coefficient of x
Note: if a = b, then a ÷ c = b ÷ c

Therefore, 12x/12 = 65 × 15/12

x = 975/12

To simplify, divide both numerator and denominator by 3, which is the GCF of 975 and 12:

x = 325/4 or, x = 81.25
