Can anyone help me with this problem ?

C

Step-by-step 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

5050

hope this !
