OK,

For the children, the milk would serve 1/4 quart per child.
For the adults, the milk would serve 1/3 quart per adult.

For 40 children, it would be 40 / 4 = 10 quarts of milk
For 12 adults, it would be 12 / 3 = 4 quarts of milk.

Together, it will be 14 quarts of milk for both.

There are 16 quarts of milk available:

16 quarts - 14 quarts = 2 quarts. (solved)</PRE>
