You are adding to the fractions together to get the whole in #6 so B is the answer
For #7 you have to change the fraction to another fraction that has a common denominator which is 8. So change3/4 into 6/8 then subtract 2 5/8-6/8. So change 2 5/8 into 1 13/8. So then subtract 1 13/8-6/8 and the answer is 1 7/8 pages.
