Answer

LCM of 18 and 88 is
792

First common multiples: 792; 1,584; 2,376; …

792 is divisible by both: 792 ÷ 18 = 44, 792 ÷ 88 = 9 — and 44 and 9 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/18 by 44 and of y/88 by 9.

18 = 2 × 32

88 = 23 × 11
