Question

Someone please help!

Answer 1

42

Explanation:

Start with the higher denominator, that is 14

Divide 14 by 6 and if the remainder is zero then 14 is the LCD

If not repeat the process with multiples of 14

14 ÷ 6 = 2 remainder 2 ← not 14, Try 28

28 ÷ 6 = 4 remainder 4 ← not 28, Try 42

42 ÷ 6 = 7 remainder 0 ← 42 is the LCD

Answer 2

I think the answer is D. 84
