Respuesta :

D
Step-by-step explanation:
Let Freddy could arrange n catalogs on the shelf.
The dimension of the shelf is:
72 over 5 inches wide.
The dimension of the catalog is:
4 over 5 of an inch thick.
n × Dimension of one catalog=Dimension of shelf.
i.e.
n×(4 over 5 inches)=72 over 5 inches
i.e.
n=72 over 5 inches/ 4 over 5 inches
i.e.
n=72/4
i.e.
n=18

d:
18, because the number of catalogs is 72 over 5 divided by 4 over 5
