Problem 1

Rosie had a piece of ribbon 350 cm long. She used some of it and had 175 cm of the ribbon left. What was the length of the ribbon that was used?

Working:

Initial length of the ribbon = 350 cm.

Length of ribbon left = 175 cm.

Length of ribbon used = Initial length – length of remaining ribbon

Length of ribbon used = 350 cm – 175 cm = 175 cm. problem1.wav
