DVD cases are 9/16 inch wide.. If Juan has 60 DVDs how many will fit on one shelf. Shelves are 2 1/2 ft long.

2 1/2 feet = 30 inches

30/(9/16)
30 * (16/9) = ____ DVDs

I don't understand the 30/(9/16) and after.

30/(9/16) means 30 inches divided by 9/16 inch.

When we divide with a fraction, we must turn it upside down and multiply.

I got 53

You are right. Juan can put 53 DVDs on the shelf.

Thank you Ms. Sue.

You're welcome, Ty.
