Question

jeremy uses 18 inches of twine for each box he packs for shipping. how many yards twines does he need to wrap 5 boxes

Answer 1

There are indeed several ways to approach this problem. The following is one:

 

The original measurement is given in inches (18 inches).

 

The answer is required in yards (1 yard = 36 inches).

 

We can immediately convert inches to yards.

 

18 inches = 18/36 yards. or 1/2 yard.

 

5 boxes will require (1/2 * 5) yards.

 

= 1/2 * 5/1 yards

 

= 5/2 yards

 

= 2 1/2 yards or 2.5 yards.

Answer 2

Fatima,

 

Again, there are several ways to do this.  As Dimensional analysis:

 

(18in * 5 boxes)(1ft/12in)(1yard/3ft)=2.5 yards.

 

Or

 

18 inches * 5 boxes = 90 inches

90 inches / 12 inches = 7.5 feet

7.5 feet / 3 feet = 2.5 yards
