Hot dogs are sold in packs of 10. Hot dog buns are sold in packs of 8. Elijah is having a party and is serving hot dogs with buns. What is the least number of hot dogs Elijah can make without having any buns or hot dogs leftover

40

10*4=40

8*5=40

4 packs of hot dogs, 5 packs of buns

You have to times 10 and 8 and find the common multiple ... and anything you times by 10 and n that no more with an added 0 at the end (10•5=50) so you just have to times 8 enough to find a number timesed by 8 that ends in a 0 ... so you might first think 8•10 to = 80 ... but you have to think of all of the other multiples ... such as 5, since 5•8=40 ... so Elijah can have 40 hot dogs without having any other buns in r hotdogs leftover
