:
%28-3a%5E2b%29%2F%2835a%5E5%29 * %2814a%5E3b%5E2%29%2F%28-9b%5E4%29
:
a^2 cancels into 35a^5 leaving:
%28-3b%29%2F%2835a%5E3%29 * %2814a%5E3b%5E2%29%2F%28-9b%5E4%29
:
a^3 cancels into a^3 leaving:
%28-3b%29%2F%2835%29 * %2814b%5E2%29%2F%28-9b%5E4%29
:
b^2 cancels into b^4 leaving:
%28-3b%29%2F%2835%29 * %2814%29%2F%28-9b%5E2%29
:
b cancels into b^2 leaving:
%28-3%29%2F%2835%29 * %2814%29%2F%28-9b%29
:
-3 cancels into -9 leaving:
%28%2B1%29%2F%2835%29 * %2814%29%2F%28%2B3b%29
:
7 goes into 35 and 14 leaving:
%281%29%2F%285%29 * %282%29%2F%283b%29 = %282%2F%2815b%29%29
