Blake wants to spend his Friday making milkshakes for his family. He knows that he needs 4 ounces of milk and 12 ounces of ice cream for each milkshake. If he has 72 ounces of milk and 192 ounces of ice cream, how much milk will be left over when he is done? Let's think first. Chain of thought:
He has enough milk to make 18 milkshakes because 72 / 4 = 18. He has enough ice cream to make 16 milkshakes because 192 / 12 = 16. He can only make 16 milkshakes because 16 < 18. He will use 64 ounces of milk because 16 x 4 = 64. He will have 8 ounces of milk left because 72 - 64 = 8.
Therefore, the answer is 8.
