Question

Veggie patties are sold in packages of 5.
Buns are sold in packages of 8.
You need about 125 veggie burgers for a school barbecue.
You do not want any patties or buns left over.
How many packages of each should you buy?
What strategy did you use to find out?

Answer 1

LCM(5,8) = 40
least multiple of 40 greater than 125 is 160
32 packs of patties
20 packs of buns

Answer 2

5 v = 8 b
5 v = 125
8 b = 125
v = 25
b = 15.625
well get 25 veggie packs and 16 bun packs
