Answer
Find out the how many games did the teams lose .
To prove
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ values}[/tex]
As given
Salem High School's winter sports teams WON 72% of their games last season.
If the teams played 50 games .
Percentage = 72%
Total value = 50
Put in the formula
[tex]72 = \frac{Number\ of\ games\ win\times 100}{50}[/tex]
[tex]Number\ of\ games\ win = \frac{72\times 50}{100}[/tex]
Number of games win = 36
Number of games teams loses = Total number of games - number of games win
= 50 - 36
= 14
Therefore the number of games team loses are 14 .
