Sandra needs 2 5/8 yards of rope she needs for her class project. She has 5 pieces of rope that are each 3/8 yards long. Does Sandra have enough rope. If not explain why.

My son wrote no she doesn’t she needs 18 more yards of rope. Can you explain this to him if this is right or wrong because I don’t know The steps of These fraction questions and I don’t understand fractions so he is struggling.

3/8 + 3/8 + 3/8 + 3/8 + 3/8 = 15/8

2 5/8 = 21/8
(2 x 8 + 5 = 21)

21/8 - 15/8 = 6/8
