We have 1265 = 15x
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, 12x12 = 65 × 1512
x = 97512
To simplify, divide both numerator and denominator by 3, which is the GCF of 975 and 12:
x = 3254 or, x = 81.25
