You can put this solution on YOUR website!
What you have so far is correct: %28y%2Fx%5E3%29%2F%28x%2Fy%5E2%29

Since you have done this, it really means:
%28y%2Fx%5E3%29 divided by %28x%2Fy%5E2%29

then you can invert the second fraction and multiply:
%28y%2Fx%5E3%29%2A%28%28y%5E2%29%2Fx%29
%28y%5E3%29%2F%28x%5E4%29

Having done this, it might have been easier if you had just subtracted the exponents:
%28x%5E-3%2Ay%5E1%29%2F%28x%5E1%2Ay%5E-2%29

x%5E%28-3-1%29%2Ay%5E%281-%28-2%29%29

x%5E-4+%2Ay%5E3
%281%2F%28x%5E4%29%29%2Ay%5E3
%28y%5E3%29%2F%28x%5E4%29
