Joelle, Gillian and Jade were each given a piece of rope of equal length. Joelle cut hers into equal lengths of 5 m, Gillian cut hers into equal lengths of 8 m, and Jade cut hers into equal lengths of 10 m. If there were no remainder in each case, find the shortest length of rope given to each of them.
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40
Multiples of 8: 8, 16, 24, 32, 40
Multiples of 10: 10, 20, 30, 40
Shortest length of rope given to each of them
= Lowest common multiple of 5 m, 8 m and 10 m
= 40 m
Answer(s): 40 m
