We have 10125 = **x**45

Cross multiplying the ratios, gives

10 × 45 = 125**x**

or, 125**x** = 10 × 45

Divide both sides by 125, which is the coefficient of **x****Note: ** if a = b, then a ÷ c = b ÷ c

Therefore, 125**x**125 = 10 × 45125

**x** = 450125

To simplify, divide both numerator and denominator by 25, which is the GCF of 450 and 125:

**x** = 185 or, **x** = 3.6
