At the beginning of a basketball season, the panthers won 20 games out of 50 games. At this rate, how many games will they win i

Anton [14]

Answer:

They will win 48 games in a 120 game season.

Step-by-step explanation:

The team won 20 games out of 50; that is a 20:50 ratio, that is equal to x:120. x is the amount of games won in the 120 game season.

Set up the ratios like this:

$\frac{20}{50}$ = $\frac{x}{120}$

cross multiply the numerators and denominators to get this:

20*120 = 50x

solve for x:

2,400 = 50x

x = 48
