Answer: 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.
