Final answer:
Sam should cut off 2-1/4 inches from her 5-1/2 inch scrap piece to achieve the 3-1/4 inches length needed for her kitchen flooring.
Step-by-step explanation:
Sam needs to cut a piece of laminate flooring to a specific size for her kitchen. The desired length of the piece is 3-1/4 inches, and she has a scrap that is 5-1/2 inches long. To find out how much Sam should cut off from the scrap, we subtract the needed length from the scrap's length:
5-1/2 inches (the scrap) - 3-1/4 inches (needed length) = 2-1/4 inches
So, Sam should cut 2-1/4 inches off the scrap piece to get the piece she needs for the flooring.
