Using proportions, it is found that there are 1680 bandages in 6 offices.
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there are 7 bandages in each pack, and each box of bandages contains 9 packs, hence the number of bandages in each box is:
N = 7 x 9 = 56.
Each office gets 5 boxes, hence the number of bandages per office is:
N = 5 x 56 = 280.
6 offices, hence the total number of bandages is:
N = 280 x 6 = 1680.
