20 Boxes × 400g — How Many 1.5 kg Bags?
Lesson 5 of 12
About this lesson
20 boxes (400 g each) must be packed into bags that hold at most 1.5 kg. The key traps: forgetting to convert kg to g, and forgetting the leftover boxes after dividing. If you just divide 20 by 3 and ignore the remainder, you get 6 — and leave 2 boxes unpacked!
