Simplify %282%2Fx%29%2F%281-%281%2Fy%29%29
First, we will deal with the denmominator, 1-%281%2Fy%29
Lets multiply each term by y%2Fy
1%28y%2Fy%29-%281%2Fy%29%28y%2Fy%29 simplifying, we get
%28y-1%29%2Fy
Now we will put the numerator and denominator back together and we have:
%282%2Fx%29%2F%28%28y-1%29%2Fy%29 Next we will multiply numerator and denominator by y%2F%28y-1%29
%28%282%2Fx%29%28y%2F%28y-1%29%29%2F%28%28y-1%29%2Fy%29%28y%2F%28y-1%29%29%29 Simplifying we get:
%282y%2Fx%28y-1%29%29%2F1 and this equals:
2y%2F%28x%28y-1%29%29
