Question

type the correct answer in the box. use numbers instead of words.
a librarian must place 248 books on shelves that can hold up to 9 books, using the fewest shelves possible.
how many shelves does the librarian need?

shelves

Explanation:

Step1: Divide total books by shelf capacity

To find the number of shelves, we divide the total number of books (248) by the number of books each shelf can hold (9). So we calculate $248 \div 9$.
$248 \div 9 = 27$ with a remainder of $5$ (because $9\times27 = 243$ and $248 - 243 = 5$).

Step2: Account for the remainder

Since we can't leave the remaining 5 books without a shelf, we need an additional shelf. So we add 1 to the quotient we got from the division.
$27 + 1 = 28$.

Answer:

28
