First calculate how many 9-inch pieces of ribbon can be cut from one 6 ft roll.
1 foot = 12 inches
⇒ 6 feet = 6 × 12 = 72 inches

Therefore, eight 9-inch pieces of ribbon can be cut from one roll.
To find how many 9-inch pieces can be cut from 5 rolls, simply multiply the number of 9-inch pieces for ribbon that can be cut from one roll by 5:
⇒ 8 × 4 = 40
Therefore, the dressmaker can cut forty 9-inch pieces of ribbon from 5 rolls.
Note: The total number of inches of ribbon the dressmaker has is:
