Don bought 3 1/2 quarts of ice-cream for a party. Four pints were eaten. How many pints remained?

3 pints

Step-by-step explanation:

In this question, we are asked to calculate the amount of pints remaining if 4 pints were eaten from 3 1/2 quarts of ice-cream

To solve this problem adequately, we need to achieve a consistency in units. This means our units must be in the same vein.

First, it must be known that one quarts is equal to 2 pints. This means that 3.5 quarts will be 3.5 * 2 = 7 pints

Now, the number of pints remaining is simply 7 pints - 4 pints = 3 pints
