Answer:
C
Explanation:
If you simplify your other ratios they all equal to 8/3
This tells you that your new ratio should also be 8/3
A common factor of 24 and 9 is 3
After you divide each number by 3 you get 8/3
A common factor of 32 and 12 is 4
After you divide each number by 4 you get 8/3
For x you know that common factor of x and 15 has to be 5 in order to simplify 15 to 3
Multiply x/5 = 8 (your simplified equation)
40/5 =8
