Question

question
a dressmaker needs to cut 9-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. how many 9-inch pieces can the dressmaker cut from 5 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?

360

how many 9-inch pieces are there in 360 inches?

Explanation:

Step1: Identify the operation

To find the number of 9 - inch pieces in 360 inches, we need to divide the total length (360 inches) by the length of each piece (9 inches). The formula for the number of pieces \(n\) is \(n=\frac{\text{Total length}}{\text{Length of each piece}}\).

Step2: Perform the division

Substitute the values into the formula: \(n = \frac{360}{9}\). When we divide 360 by 9, we know that \(9\times40 = 360\), so \(\frac{360}{9}=40\).

Answer:

40
