  3. "Good morning, Mrs. Jade," said Mrs. Smith. "May I borrow your 5-quart pail today? I am going to the store to buy 4 quarts of mile, and my pail isn’t big enough. It holds only 3 quarts."

    "I was just about to go to the store myself to buy 4 quarts too," said Mrs. Jade. "Suppose you take my 8-quart, have it filled and we’ll divide it when you get back."

    Mrs. Smith returned from the store with the 8-quart pail full of milk. Then, with the help of the 5-quart pail and the 3-quart pail, Mrs. Jade divided the milk into 2 equal parts.
