A baseball pitcher won 80% of the games he pitched. If he pitched 35 ballgames, how many games did he win?

The whole is 35.

The percent is 80%.

Let n represent the part.

Write a proportion and find the cross products to solve for n.

=

100n = 35 ×80

100n = 2,800

100n ÷ 100 = 2,800 ÷ 100

n = 28


80% of 35 is 28.

28 games.
