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 10 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?

Answer 1

You have 10 rolls and each is 6 feet so therefore you have 60 feet of ribbon. Convert that to inches you need to multiply by 12 so 60 x 12 = 720 inches of ribbon.
If the dress maker needs 18 inch pieces you divide to 720 by 18.
720 divided by 18 will give you 40 pieces.

Final answer:

The dressmaker will get 40, 18-inch pieces of ribbon from 10, 6 foot rolls.

Answer 2

From 10 rolls of 6-feet-long ribbon, the dressmaker can cut a total of 40 pieces of 18 inches each.

Calculating the total length of ribbon:

Each roll of ribbon is 6 feet in length. Since there are 10 rolls:

Total length of ribbon in inches = (Length of one roll in feet * 12 inches per foot) * Number of rolls

Total length of ribbon = (6 feet * 12 inches/foot) * 10 rolls

Total length of ribbon = 72 inches/roll * 10 rolls

Total length of ribbon = 720 inches

So, the dressmaker has a total of 720 inches of ribbon in 10 rolls.

Calculating the number of 18-inch pieces the dressmaker can cut:

The dressmaker needs to cut 18-inch pieces from this total length.

Number of 18-inch pieces = Total length of ribbon / Length of each 18-inch piece

Number of 18-inch pieces = 720 inches / 18 inches

Number of 18-inch pieces = 40

Therefore, from 10 rolls of 6-feet-long ribbon, the dressmaker can cut a total of 40 pieces of 18 inches each.
