A proportion is a fraction of a total amount.

In this problem, considering the proportions of the red and of the blue teams, the number of games they are expected to win is given by:

• R = 0.55 x 180 = 99.

• B = 0.6 x 180 = 108.

108 - 99 = 9, hence the fan should expect the red team to win 9 less games.
