Jacob will need eleven shelves in order to stack all the books

Explanation:

(9) = 1 shelf

(18) = 2 shelves

(27) = 3 shelves

(36) = 4 shelves

(45) = 5 shelves

(54) = 6 shelves

(63) = 7 shelves

(72) = 8 shelves

(81) = 9 shelves

(90) = 10 shelves This isn't enough because he has 6 more ... therefore

In order to fit 96 books on the library shelves Jacob needs to stack 11 shelves.

not social studies but ill answer anyway.

You divide 96/9 you get 10.66 ...

so he needs eleven shelves
