Question

Miley and Cole ended up making the same number of biscuits for a bake sale at school, even though Miley made them in batches of 7 biscuits and Cole made them in batches of 11 biscuits. What is the smallest number of biscuits each must have baked?

Answer 1

The smallest number is 77

Explanation:

The LCM of 7 and 11 is 77 and I did LCM because it says "smallest number" which means I have to do LCM.

Answer 2

77

Explanation:

They each start at 0. Miley will be making them in groups of 7 and Cole 11.

Miley: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77.

Cole: 11, 22, 33, 44, 55, 66, 77.

The answer is 77.
