Students are planning a hotdog sale. They expect to sell about 250 hotdogs. The local grocery store sells wieners in packages of 12 and buns in packages of 8. How many packages of wieners and buns should the students buy if they want to make about 100 hotdogs, with no wieners or buns left over?

You want to find the least common multiple of 12 and 8 that is closest to 100.

12=3*2*2

8=2*2*2

so LCM(12,8)=24

List multiples of 24:

24

48

72

96

120
 

96 is the closest to 100, so the students want to buy 96/12=8 packages of hotdogs and 96/8=12 packages of buns.
