A. 30

B. 18

C. 15

D. 10

2/3 = 20/30

4/5 = 24/30

7/10 = 21/30

So, the answer would be 30.

Answer: 30

The Prime Factorization of 3,5,10 is:

3 = 1 x 3

5 = 1 x 5

10 = 2 x 5

Lets Multiply it:

We already have a 5, so we can only use one of the fives.

1 x 1 x 2 x 3 x 5 = 30

the answer is 30
