Question

There are 4 quarts in a quart and 4 quarts in a gallon. A baker needs 1 cup of milk for each batch of muffins he makes. He has 3 gallons of milk and wants to make as many batches as possible. How many batches of muffins will the baker make?

Answer 1

Answer:  48 batches

======================================

Work Shown:

4 cups = 1 quart .... given info

4*(4 cups) = 4*(1 quart) ... multiply both sides by 4

16 cups = 4 quarts

4 quarts = 1 gallon .... given info

16 cups = 1 gallon .... replace "4 quarts" with "16 cups"

3*(16 cups) = 3*(1 gallon) ... multiply both sides by 3

48 cups = 3 gallons

The baker will get 48 cups out of 3 gallons of milk. Since each batch needs 1 cup of milk, this means the baker will be able to make 48 batches of muffins.
