-2 + 15 + 5 The indicated sum is 18 .

The LCM of 15 (which is 3*5) and 18 (which is 2*3^2) is 90 (which is 2*3^2*5).

27 * 5 / 18 = 15/2 = 7.5

22/5 ÷ 18 = 2/15

15/18 × 12/5 = 2/1 or 2

5/6 + 2/18 = 15/18 + 2/18 = 17/18

Factors: 15 = 3 x 5, 18 = 2 x 3 x 3. The LCM of two numbers = their product divided by their HCF. In this instance the product is 270 and the HCF is 3 so the LCM is 90.

18/11 x 5/12 is 15/22
