alrighty…i think its lilke this:

5 over 15 and 8 over x

then cross multiply to get:

5x = 15 (8)

Then:

5x = 120 ( i got 120 from 15 times 8)

then you need to get x on its own:

5x = 120

—- —-

5 5

the 5 over 5 cancels out leaving x on its own and then you have to take 120 divided by 5 to get 24….your final answer is

x = 24

Hope that helped…. 😀
