Let's solve this step by step. We have 80 pears total, and we need to put 9 pears in each box. This is a division problem where we need to find both the quotient and remainder. To find how many boxes we need, we divide the total number of pears by the number of pears per box. So we calculate 80 divided by 9. This will give us both the number of full boxes and any remaining pears. Now let's perform the division. We need to find how many times 9 goes into 80. Nine times 8 equals 72, and nine times 9 equals 81, which is too big. So 9 goes into 80 exactly 8 times. When we subtract 72 from 80, we get 8 as the remainder. Therefore, 80 equals 9 times 8 plus 8.
