Manuela has a piece of red ribbon 7 1/2 feet long. She cut the ribbon to have one piece 1 ¾ feet long. How long is the piece of ribbon that is left? A. 5 ½ feet We can subtract the two whole numbers to give us 6 feet. When we subtract the fractions from each other that gives us 1/2. When we take 1/2 from 6 we get the amount of ribbon left.

B. 6 ¼ feet We can subtract the two whole numbers to give us 6 feet. When we subtract the fractions from each other that gives us ¼. We combine the two numbers and we get the amount of ribbon left.

C. 6 feet We can get the amount of ribbon left by just subtracting the two whole numbers in the problem.

D. 5 ¾ feet. We can subtract the two whole numbers to give us 6 feet. When we subtract the fractions from each other that gives us ¼. When we take ¼ from 6 we get the amount of ribbon left.
