Answer:
If the students drank 60 quarts of milk at lunch, they drank 120 pints of it.
Step-by-step explanation:
A quarter is a unit of volume that is equal to a quarter part of a gallon, while a pint is one eight part of the same. So, there's a proportion of 4/8 between a quarter and a pint with respect to a gallon, which means that a pint is the half of a quart. So, if the students drank 60 quarts, they drank 120 pints of milk.
