3 packs of plates and 2 packs of cups

Ernest Moody · Answer 2

Answer:John is incorrect, because if you multiply 12 by 2 (packs of plates) you get 24 plates, and that is divisible by 8, and so you divide 24 by 8, and you get 3 packs of cups. So, you need 2 packs of plates and 3 packs of cups at least.
