Answer:
18, because the number of catalogs is 72/5 ÷ 4/5
Step-by-step explanation:
The answer is the last option because in total, the shelf is 72/5 inches wide. Given each catalog is 4/5 inch wide, and we want to find how many catalogs can fit in the shelf, we have to divide 72/5 by 4/5. When we divide 72/5 by 4/5, we get 18.
