3y%5E3%2Fx%5E2-2x%5E8%2Fy%5E12 (Sometimes you can stop here)The LCD is x^2y^12
y%5E12%283y%5E3%29%2F%28x%5E2y%5E12%29-%28x%5E2%29%282x%5E8%29%2F%28x%5E2%2Ay%5E12%29

3y%5E15%2F%28x%5E2%2Ay%5E12%29-2x%5E10%2F%28x%5E2%2Ay%5E12%29
%283y%5E15-2x%5E10%29%2F%28x%5E2%2Ay%5E12%29 (other times they want it to be written as a single fraction like this.)
Happy Calculating!!!
