To do complex fractions, do whats on the bottom and top and then divide the bottom and top fractions and you should get your answer. For example in a equation like 1/2 + 1/2/ 1/4 + 1/4, you would have to solve the equations in the denominator and numerator. So 1/2 + 1/2 is equal to a whole, or 1. So now that we've solved the numerator's equation, the problem is now, 1/1/4 + 1/4. Now I solve for the denominator. 1/4 + 1/4 is equal to 2/4. So now my equation is 1/2/4. Finally I divide 1 by 2/4, which will give me 2. Hope this helps you.
