Answer 1

Hi Catty!

Explanation:

A roll of ribbon is 9 feet long, which is equal to 9 feet x 12 inches/foot = 108 inches.

So, the dressmaker has 5 rolls of ribbon x 108 inches/roll = 540 inches of ribbon in total.

Each roll of ribbon is 9 feet long, which is equal to 9 feet * 12 inches/foot = 108 inches.

So, from one roll, a dressmaker can cut 108 inches / 12 inches/piece = 9 pieces of 12-inch ribbon.

Therefore, from 5 rolls, the dressmaker can cut 9 pieces/roll * 5 rolls = 45 pieces of 12-inch ribbon.

Answer 2

540 inches

45 pieces

===========================================

Work Shown:

1 roll = 9 feet of ribbon

5 rolls = 5*9 = 45 feet of ribbon

1 foot = 12 inches

45 feet = 45*12 = 540 inches

The dressmaker has 540 inches of ribbon in total.

Divide this over 12 to find out how many 12-inch pieces we can get out of this total

540/12 = 45 pieces

Or note that the 12-inch pieces are really 1 foot each. Since we have 45 feet of ribbon total, we can get 45 pieces that way.
