Katie has read 32 percent of a book. If she has read 80 pages, how many more pages does Katie have left to read?A 40
B 170
C 200
D 250

Answers

You need to divide 80 by 0.32 (this is your percent) to find the total amount of pages, which is 250. now subtract 80 from 250 to find the remaining pages, which is 170. The answer is B.

You dive 80 by 32 and 32 which means that ever 2.5 pages is 1 percent of the book so you multiple by 100 and get 250 pages

$(1)/(4) - (1)/(5)$

First, you have to find a common denominator
