Fiona, Hilda and Vanessa were each given a piece of ribbon of equal length. Fiona cut hers into equal lengths of 3 m, Hilda cut hers into equal lengths of 6 m, and Vanessa cut hers into equal lengths of 10 m. If there were no remainder in each case, find the shortest length of ribbon given to each of them.
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
Multiples of 6: 6, 12, 18, 24, 30
Multiples of 10: 10, 20, 30
Shortest length of ribbon given to each of them
= Lowest common multiple of 3 m, 6 m and 10 m
= 30 m
Answer(s): 30 m
