I think you mean:

%28%28x%2F2%29%2B%28y%2F3%29%29%2F%28%282%2Fx%29-%283%2Fy%29%29

The common denominator in the numerator expression is 6, so


%28%283x%2B2y%29%2F6%29%2F%28%282%2Fx%29-%283%2Fy%29%29


The common denominator in the denominator expression is xy, so


%28%283x%2B2y%29%2F6%29%2F%28%282y-3x%29%2Fxy%29


Now invert and multiply


%28%283x%2B2y%29%2F6%29%28xy%2F%282y-3x%29%29


%283x%2B2y%29xy%2F6%282y-3x%29%29%29


%283x%5E2y%2B2xy%5E2%29%2F%2812y-18x%29
