There are 4 cups in 1 quart and 4 quarts in 1 gallon. A baker need 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? Complete the statement.
The baker will make ___ batches of muffins.
The baker has 3 gallons of milk, which is equal to 3 * 4 = <<3*4=12>>12 quarts of milk.
