Patricia packages eggs into containers that hold a dozen eggs. She is allowed to take home any eggs that are left over. Today, Patricia has 650 eggs to package. Will she be able to take any eggs home? If so, how many?

• No; I divided 650 by 12 to get 55 R 0. This means that she will fill 55 containers.

• Yes, 2 eggs; I divided 650 by 12 to get 45 R 2. This means that she will fill 45 containers and have 2 eggs left over, so she can take those home.

• No, I divided 650 by 12 to get 54 R 0. This means that she will fill 54 containers and have 0 eggs left over.

• Yes, 2 eggs; I divided 650 by 12 to get 54 R 2. This means that she will fill 54 containers and have 2 eggs left over, so she can take those home.
