%284%2B%282%2Fx%29%29%2F%28%28x%2F4%29%2B%281%2F8%29%29
in first step you have to find common denominator for
4%2B%282%2Fx%29=4x%2Fx%2B%282%2Fx%29=+%284x%2B2%29%2Fx=+2%282x%2B1%29%2Fx
and
%28x%2F4%29%2B%281%2F8%29=%282x%2F8%29%2B%281%2F8%29=%282x%2B1%29%2F8
then you get:
%282%282x%2B1%29%2Fx%29%2F%28%282x%2B1%29%2F8%29
to divide fractions it means you have to multiply first by inverse of second
%282%282x%2B1%29%2Fx%29%2A%288%2F%282x%2B1%29%29= 16%2Fx
