Question

The royals softball team played 75 games and won 55 of them. What percent of the games did they lose (round to the nearest hundred)

Answer 1

They lost 20 games, 20/75 which is .26666667 rounded and put into a percent would be 27%

Answer 2

If they won 55 of the games, that means they lost the rest of the 75.  So,
75 - 55 = 20 games lost.  To find the percentage of 20 out of 75, you set up a proportion:

$\frac{20}{75}=\frac{x}{100}$

where x = the percentage of games lost.  Cross multiply and divide to isolate the x:

$\frac{20}{75}=\frac{x}{100}\\75x=2000\\75x/75=2000/75\\x=26.6666667$

Rounded to the nearest hundredth, the Royals lost 26.667 % of their games.
