solve for variables
20/y=15/10=x/8

Split it into two separate equations.
20/y=15/10
Solve for Y by multiplying both sides by y and 10.
200 = 15y
Likewise, do the same for the second part.
15/10=x/8
Multiply both sides by 80.
120 = 10x
You should be able to do the rest. I hope this helps. Thanks for asking.
