Question

Hot dogs are sold in packages of 10. Hot dog buns are

sold in packages of 8. What is the least number of
packages of each that need to be purchased so every
hot dog you buy for a picnic will have a bun?

Answer 1

4 Hot dogs packages and 5 hot dog buns packages.

Explanation:

This question seems to be regarding the LCM or the least common multiple. Least common multiple is found by figuring out the first time when both numbers, in this case 10 and 8 have the multiple. You can do this by setting up a table with the multiples of each number.

8 | 16 | 24 | 32 | 40

10 | 20| 30 | 40

We can see that the LCM is 40 so we can see that we need 4 Hot Dog packets and 5 buns packets.
