Question

Hot dogs come packed 10 in a package. Hot dog buns come packed 8 in a package. If we want one hot dog for each bun for a picnic with none left over, what is the least amount of each we need to buy? How many

packages of each item would we have to buy?

Answer 1

40 individual hotdogs and 40 individual hot dog buns

4 hotdog packages and 5 hot dog bun packages

Explanation:

multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80

multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80

Least common multiple (LCM) is 40

10*4=40

8*5=40
