Answer :
45 pieces can the dressmaker cut from 5 of these rolls of ribbon.
Mathematical expression:
When we validly combine numbers and variables, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combination of mathematical symbols is called a mathematical expression.
Here we have to find the number of 12-inch pieces can the dressmaker cut from 5 of these rolls of ribbon.
We are provided the length of the ribbon, which is 9 feet.
As we know that
1 feet = 12 inches
So rolls of 9 feet can make 9 pieces of 12 inches.
So 5 of these rolls of ribbon can make = 5 × 9 = 45 pieces.
Therefore we get 45 pieces.
