I'll assume the problem is given as:
%28w%2Br%29%2Fwr%5E2+%2B+%284w%2Br%29%2Fw%5E2r
Get to a common denominator.
%28w%2A%28w%2Br%29%29%2F%28w%5E2r%5E2%29+%2B+%28r%2A%284w%2Br%29%29%2F%28w%5E2r%5E2%29
%28w%5E2%2Bwr%29%2F%28w%5E2r%5E2%29+%2B+%284rw%2Br%5E2%29%2F%28w%5E2r%5E2%29
%28w%5E2%2B4rw%2Br%5E2%29%2F%28w%5E2r%5E2%29
