Question

jacob has 96 books to stack on library shelves. each half can hold 9 books.how many shelves will he need to stack all his books

Answer 1

11 shelves.

Divide 96 by 9

96 ÷ 9 = 10.6

Since 10.6 rounds to 11, and it is more than 10, we will need 11 shelves to store the books, since there is no such thing as a half-bookshelf here.
