Question

Part 1: Pizza is served in the school cafeteria every fourth school day. Tacos are served every third school day. Both pizzas and tacos are served today. In how many school days will pizza and tacos be served on the same day again? Part 2: If the pattern continues, will pizza and tacos be served on the same day in 21 school days? Explain why or why not.

Answer 1

No because 21 times 4 is 84 and 21 times 3 is 61. If you do the math, 84 and 61 wouldn't add up correctly compared to the 3 and 6.
