George and 4 friends are building a two-story clubhouse using bricks. In six days they placed 905 bricks. If each person placed an equal number of bricks how many bricks did each person place?
There are 5 people total (George plus 4 friends). If they each placed an equal amount out of the 905 bricks placed, then we need to divide this number between the five. To do so, we divide 905 by 5.
