question
a dressmaker needs to cut 18-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. how many 18-inch pieces can the dressmaker cut from 15 of these rolls of ribbon?

before you try that problem, answer the question below.

how many inches of ribbon does the dressmaker have, in total?
1080
how many 18-inch pieces are there in 1080 inches?

Explanation:

Step1: Identify the total inches per roll

Since 1 foot = 12 inches, a 6 - foot roll has $6\times12 = 72$ inches.

Step2: Calculate total inches for 15 rolls

Multiply the inches per roll by the number of rolls: $72\times15 = 1080$ inches (this is given, but for the second part)

Step3: Find number of 18 - inch pieces

To find how many 18 - inch pieces are in 1080 inches, divide 1080 by 18: $\frac{1080}{18}=60$

Answer:

60
