A DVD case is 9/16 in. Thick. How many of these cases will fit on a shelf that is 1 1/2 ft wide

1 1/2 feet = 18 inches

Divide 18 by 9/16

32

Right.

A math book is 0.5 in thick ow many will fit on a 36 in shelf

Thanks! I hope you have a great day!

To find out how many DVD cases will fit on a shelf, we need to compare the thickness of the DVD case to the width of the shelf.

First, let's convert the thickness of the DVD case to feet. Since there are 12 inches in a foot, the thickness of the DVD case can be calculated as (9/16) / 12 = 0.046875 feet.

Next, we convert the width of the shelf to feet. In this case, the width of the shelf is given as 1 1/2 ft, which can be written as 1.5 ft.

Now, we divide the width of the shelf by the thickness of the DVD case to find the number of cases that can fit. So, 1.5 ft / 0.046875 ft = 32.

Therefore, 32 DVD cases will fit on a shelf that is 1 1/2 ft wide.
