Alyssa made 6 batches of cookies. Each batch contained 12 cookies. She wants to pack the cookies into boxes with exactly 10 cookies per box. Which explains how many full boxes Alyssa will be able to pack?

• 72 full boxes, because 6 × 12 is 72 with no left over cookies.

• 8 full boxes, because 72 ÷ 10 is 7 with a remainder of 2 left over cookies.

• 7 full boxes, because 72 ÷ 10 is 7 with a remainder of 2 left over cookies.
