A baseball team played 140 regular season games. The ratio of the number of games they won to the number of games they lost was 2/5

. How many games did they​ win? How many games did they​ lose?

Let's represent the number of games won as 2x and the number of games lost as 5x.

According to the given ratio, we have:

2x / 5x = 2 / 5

Cross multiplying, we get:

5 * 2x = 2 * 5x
10x = 10x

This equation is true for all values of x, so we cannot determine the exact number of games won and lost based on the ratio alone.

However, since the team played 140 games in total, we can set up the equation:

2x + 5x = 140
7x = 140
x = 20

Therefore, the team won 2 * 20 = 40 games and lost 5 * 20 = 100 games.
