Answer

LCM of 75 and 85 is
1,275

First common multiples: 1,275; 2,550; 3,825; …

1,275 is divisible by both: 1,275 ÷ 75 = 17; 1,275 ÷ 85 = 15 — and 17 and 15 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/75 by 17 and of y/85 by 15.

75 = 3 × 52

85 = 5 × 17
