Answer 1

M=3/4J or J=4/3M

Explanation:

3:4, 9:12, and 15:20 are ratios that are equal to each other.

If you multiply 3:4 by 3 you get 9:12 and if you multiply it by 4 you get 15:20

another way to check is to plug the numbers in.

3 is 3/4 of 4

9 is 3/4 of 12

15 is 3/4 of 20

so the equation is true
