4xcubed/2y)(10ysquared/36x):
:
%284x%5E3%29%2F%282y%29*%2810y%5E2%29%2F%2836x%29
:
Cancel out the coefficients first:
%282x%5E3%29%2F%28y%29*%285y%5E2%29%2F%2818x%29
:
Notice 2 will cancel into 18 leaving:
%28x%5E3%29%2F%28y%29*%285y%5E2%29%2F%289x%29
:
x cancels into x^3, and y into y^2, resulting in:
x^2)*%285y%29%2F%289%29
:
which is:
5x%5E2y%2F9
:
how about this? did it make sense to you?
