Question

Joelle sorted her books into separate piles. She placed 4 books in each pile. If she has 160 books, how many piles did she make?

Answer 1

Joelle made 40 piles.

Explanation:

Since there are 4 books in each pile and Joelle has 160 books, we can determine how many piles (p) she made by dividing 160 by 4:

(4 books * # of piles) = 160 books altogether

(4p = 160) / 4

p = 40

Thus, Joelle made 40 piles.
