Final answer:
The team won 17 out of 20 games played, which is equivalent to 85%.
Step-by-step explanation:
To find the part of the games played that the team won, we need to subtract the number of games lost from the total number of games played. In this case, the team played 40 games and lost 6, so the number of games won is 40 - 6 = 34.
To express this as a part, we can write it as a fraction: 34/40. This can be simplified to 17/20, which means the team won 17 out of 20 games played.
Therefore, the team won 17/20 or 85% of the games played.
