Question

Sally's soccer team played 40 games and won 15 of them. What percent did the team win?

Answer 1

(They are proportional measures, the rule of three is made (directly proportional)

games _____ won (%)
40 ------------------ 100
15 ------------------ y

Solving:


`(40)/(15) = (100)/(y)`
multiply cross

`40*y = 15*100`

`40y = 1500`

`y = (1500)/(40)`

`y = 37.5 \to\:\boxed{37.5\%}\end{array}}\qquad\quad\checkmark`

Answer 2

Sally's soccer team played 40 games and won 15 games. What percent of games did the team win?

To find out what percent of the games that Sally's team won, we can turn this into a fraction. The fraction
`(15)/(40)` represents the 15 games that the team won out of all the games they played.

We can reduce this fraction by dividing both the numerator and denominator by the greatest common factor of 15 and 40 using 5.

We now have our reduced fraction which is
`(3)/(8)`.

3 ÷ 8 = 0.375

0.375 × 100 = 37.5%

Therefore, Sally's soccer team won 37.5% of the games that they played.
