Question

Suppose that hot dog came in packs of 12 and buns come in packs of 10. Alan bought the same number of hot dogs as buns. It was the least number of each for which this was possible

Answer 1

To answer this problem, we need to use LCM

10 12 / 2
5 6 / 2
5 3 / 3
5 1 /5
1 1

2x2x3x5 = 60

Answer: Alan bought 5 hot dog packs (12 x 5 = 60) and 6 bun packs (10 x 6 = 60)
