D. 9/2÷18
Let
Total length of box = 18 inches
Thickness of each book = 2/9 inches
Number of books that will fit into the box = x
Number of books that will fit into the box = Total length of box ÷ Thickness of each book
x = 18 ÷ 2/9
= 18 × 9/2
= 162/2
= 81 books
The correct answer is A. 18÷2/9
18=3+36x-50x-55
18=3-14x-55
18=-14x-52
70=-14x
x=-5
2x3=6
3x2=6
6 divided by 2=3
6 divided by 3=2
