Hank has read 25 percent of his book. If Hank has read 150 pages, which equation can be used to find the total number of pages in the book?

Question

A.

B.

C.

D.

Answer 1

Let's look at another approach. 25% is 25/100=1/4. That means 150 pages is a quarter of the book, so the book must have 4 times as many pages=4*150=600. The only answer to get 600 pages is A. 150/600=1/4.
