sue has 7/8 of her book left to read. If she reads another 2/7 of the book, how much of the book will she have left?
2 answers:
Let B = how much of the book she has left to read. B = 7/8 - 2/7 B = (49 - 16)/56 B = 33/56 Sue has another 33/56 left of the book to read.
First you have to make the fractions equal. That gives you 49/56 and 16/56. Then you add them together and get 65/56. So I guess she finishes the book. (not completly sure, werid) Hope this helps
