Answer:
80% of the people on the trip are children.
Step-by-step explanation:
To determine the percentage of the people on the trip that are children,
First, we will determine how many of the people are children.
From the question,
There are 5 adult chaperones for every group of 20 students, that is, out of 25 people, 5 are adult chaperones and 20 are students.
From the question, there are 150 people in total in total.
Let the number of children be x
If there are 20 students (children) in 25 people
Then, there will be x children in 150 people
x = (150 × 20) / 25
x = 120
Hence, there are 120 children.
To determine the percentage of the people on the trip that are children,
we will divide the number of children by the total number of people and then multiply by 100%
Number of children = 120
Total number of people = 150
∴ The percentage of the people on the trip that are children is
(120/150) × 100% = 0.8 × 100% = 80%
Hence, 80% of the people on the trip are children.
