Maria has 9 boxes that each weigh 78 pound.

how many pounds do the boxes weigh altogether?

enter your answer as a mixed number in simplest form by filling in the boxes.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The mode of the numbers is 29.
