Question

Kakashi is filling his new bookshelf. The shelf holds 40 books. If he fills the bookshelf 4/5 of the way, how many books will Kakashi need?

Answer 1

Answer: 8 books

Explanation:

First, she has 40 books.

1) Then she fills 4/5 of it. 4/5 of 40 is 32.

2) (4/5) x (40) = 32.

3) 40 - 32 = 8

4) So she needs to add 8 books.

Hope this helps :)
