Freddy has a shelf that is 72 over 5 inches wide. How many catalogs can Freddy arrange on the shelf if each catalog is 4 over 5 of an inch thick? (5 points)
11, because the number of catalogs is 72 over 5 divided by 5 over 4
12, because the number of catalogs is 72 over 5 multiplied by 4 over 5
16, because the number of catalogs is 72 over 5 multiplied by 5 over 4
18, because the number of catalogs is 72 over 5 divided by 4 over 5
To find the number of catalogs that can be arranged on the shelf, we need to divide the width of the shelf by the thickness of each catalog.
The width of the shelf is 72/5 inches and the thickness of each catalog is 4/5 of an inch.
The number of catalogs is:
(72/5) / (4/5) = (72/5) * (5/4) = 72/4
Let's simplify the fraction:
72/4 = 18
Therefore, the number of catalogs that Freddy can arrange on the shelf is 18.
