the store does not sell parts of a pack and yadira's mom wants the same number of hot dogs as hot dog buns.
what is the smallest total number of hot dogs that yadira's mom can purch

Find the least common multiple of 12 and 9:

9, 18, 27, 36, 45, 54

12, 24, 36, 48, 60

The smallest number ( least common multiple) for both 9 and 12 is 36.

This means she needs to buy 36 hot dogs and rolls, which would be 4 packages of hot dogs and 3 packages of hot dog rolls.
