Question

There are 64 people coming to your party and each person will need one cup. How many packages of cups should you buy if one package contains 23 cups?

Answer 1

3 packages

Explanation:

64/23 = 2 18/23, so 3 packages will be needed.

Alternately, 23 + 23 = 46, and 64 - 46 = 18.

So 2 packages will not be enough; 3 packages will do.
