There are 160 pages in a book.15% of the pages having pictures on them. How many Pages do not have pictures on them?

We need to find out how much 15 percent of 160 is. Then, we can subtract that amount by 160. We can use proportions to solve this. We can set up our first fraction with x/160. Our next fraction can be 15/100. We can cross multiply, 160*15. 160*15 is 2,400. 2,400/100 is 24. This means 24 pages have pictures in them. 160-24 is 136. 136 pages do not have pictures on them.
