How much ribbon for my class?

Question

My class needs 27 pieces of ribbon, each piece 2 feet, 3 inches long. How many yards of ribbon does my class need?

Answer 1

1 feet = 12 inches
3 inches = 0.25 feet
1 yard is 3 feet
convert 2 feet 3 inches to 2.25 feet
27 pieces x 2.25 feet = 60.75 feet
60.75 feet / 3 feet = 20.25 yards of ribbon
