Question

Hannah poured 4 pints of liquid into the 5 quart punch bowl. How many more quarts should Hannah add to fill the bowl?

Answer 1

`3` more quarts

Explanation:

A very long time ago I learned (to be recited in a sing-song voice):

2 cups, 1 pint;
2 pints, 1 quart;
4 quarts, 1 gallon

So the `4` pints Hannah poured into the bowl is the same as `2` quarts, leaving space for `3` more quarts in the 5 quart bowl.
