2/5 x 15/18 = 1/3
-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

15 x 8 = 120
-15 - 5 - -2 = -20 + 2 = -18
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
-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).
The prime factor of 5 is 5Prime factors of 15 are 3 x 5Prime factors of 18 are 2 x 32The LCM of 5, 15, and 18 is 2 x 32 x 5= 2 x 9 x 5 = 90
the answer is 5-8.
27 * 5 / 18 = 15/2 = 7.5
