before you try that problem, answer the question below.

540
how many 9-inch pieces are there in 540 inches?

Explanation:

Step1: Convert feet to inches

We know that 1 foot = 12 inches. Each roll is 9 feet, so the length of one roll in inches is $9\times12 = 108$ inches.

Step2: Find total inches for 5 rolls

There are 5 rolls, so total inches is $108\times5 = 540$ inches (this matches the given value).

Step3: Calculate number of 9 - inch pieces

To find how many 9 - inch pieces are in 540 inches, we divide total inches by length of each piece: $\frac{540}{9}=60$.

60
