Question

Ronald will grill hot dogs at an upcoming cookout. Hot dogs come in packs of 10, while the buns come in packs of 8. What is the least number of each type of package Ronald can buy so that he will have the same number of hot dogs and buns?

Answer 1

Ronald should buy 4 packs of hot dogs and 5 packs of buns to have the same number of hot dogs and buns.

Step-by-step explanation:

In order to have the same number of hot dogs and buns, Ronald needs to find the least common multiple (LCM) of 10 and 8. The LCM of 10 and 8 is 40.

This means that Ronald needs to buy 40 hot dogs and 40 buns. Since hot dogs come in packs of 10, he needs to buy 4 packs of hot dogs. And since buns come in packs of 8, he needs to buy 5 packs of buns.

Therefore, Ronald should buy 4 packs of hot dogs (total of 40 hot dogs) and 5 packs of buns (total of 40 buns) to have the same number of hot dogs and buns.
