Final answer:
Approximately 33.33% of the tramping team are parents.
Step-by-step explanation:
To find the percentage of parents in the tramping team, we need to determine the total number of people in the team and the number of parents in the team. The team consists of 6 students, 2 teachers, and 4 parents, which makes a total of 6 + 2 + 4 = 12 team members.
Now, to find the percentage of parents, we divide the number of parents (4) by the total number of team members (12) and multiply by 100. So the percentage of parents in the tramping team is (4/12) × 100 = 33.33%. Therefore, approximately 33.33% of the tramping team are parents.
