%28%289x%5E2-16y%5E2%29%2Fxy%29%2F%28%283%2Fy%29-%284%2Fx%29%29 After factorising the numerator and simplifying the denominator, we get,

%28%283x%2B4y%29%283x-4y%29%2Fxy%29%2F%28%283x-4y%29%2Fxy%29. This means the numerator divided by the denominator. For dividing, we multiply the numerator by the inverse of the denominator. So,

%28%283x%2B4y%29%283x-4y%29%2Fxy%29%2A%28xy%2F%283x-4y%29%29%29 = %28%283x%2B4y%29%283x-4y%29xy%29%2F%28xy%2A%283x-4y%29%29 =

3x%2B4y Answer. I hope this is clear to you now.
