Steps for finding the solution

We have 10/125 = x/45

Cross multiplying the ratios, gives

10 × 45 = 125x

or, 125x = 10 × 45

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

Therefore, 125x/125 = 10 × 45/125

x = 450/125

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

x = 18/5 or, x = 3.6
