The cards can be divided equally between 3 players or 5 players. Could there be 50 cards? Explain using reasoning about divisibility.
No. 50 is divisible by 5 (50 ÷ 5 = 10) but not divisible by 3 (50 ÷ 3 = 16 remainder 2). For a number to be divisible by both 3 and 5 it must be divisible by 15. 50 is not divisible by 15, so it cannot be divided equally among both 3 and 5 players.
