Question: If 7 teams participate in a league tournament,____________number of matches will be played.

The correct answer is –

If 7 teams participate in a league tournament, the number of matches played can be calculated as follows:

First, we need to know that each team will play against every other team once.

Therefore, we can use the formula:

number of matches = (number of teams × (number of teams – 1)) / 2

Substituting 7 for the number of teams, we get:

number of matches = (7 × (7 – 1)) / 2 number of matches = (7 × 6) / 2 number of matches = 21

Therefore, in a league tournament with 7 teams, a total of 21 matches will be played.
