Uniform Rates type situation, food consumption, but you do not know how much food in any given unit. Just call this 1 lot of food.

This solution process is shown without explanation:

Let r be the consumption rate for 1 student in LOT per MONTHS.
Let t be time in MONTHS (not days) for the lesser quantity of students.

.
Solve for t; and make what conversion you want.
