Yadira's mom is buying hot dogs and hot dog buns for the family barbecue. hot dogs come in packs of 12 and hot dog buns come in packs of 9. 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 purchase?

36 is the smallest total number of hot dogs

Ah hah ! People on are always
asking us where they can
use this stuff in real life. HERE is a
perfect example of where
you can use Least Common Multiple in
real life . . . when your buying
hot dogs and buns !!

When they come in packs , with
different numbers in each pack
but you want to win up with the same
number of each item,
the number of each item that you
should buy is the LCM of
the number in each pack

yadira's mom absolutely aced her math
in middle school , so she
knows right away that the LCM of 9
and 12 is 36 . this tells her
she would buy 36 hot dogs ( 3
packs ) and 36 buns ( 4 packs)

I hope it helps

The correct answer is: 2

The answer is 225 miles per 4.5 hours. hope this ; )
