Erin has a rectangular piece of pine that is 9 inches long and 4 inches wide. For some unknown reason she wants to cover it with ribbon that is ¼ wide. How many inches of that ribbon will she need to cover the wood?

Erin will need 16 inches of that ribbon to cover the wood.

Step-by-step explanation:

To solve this problem you need to divide the width of the pine by the width of the ribbon.

4 divided by 1/4 = 16

also you can do a reverse check by multiplying 1/4 (the width of the ribbon) by 16 Inches (the width of the ribbon she will need to cover the entire pine.

1/4 x 16 = 4.

The answer gives the width of the pine, 4 inches.
