Question

Required that there must be chaperones for every 25 how many chaperones must there be for 80 students

Answer 1

6 chaperones on 80 students.

Explanation:

Here is the complete question: School guideline required that there must be 2 chaperones for every 25 students on a school trip. how many chaperones must there be for 80 students?

Given: There must be 2 chaperones on every 25 students.

Now, we will use unitary method to solve.

We know 2 chaperones = 25 students

∴ one student required
`(2)/(25)\ chaperones`

Next for 80 students, we require=
`(2)/(25) * 80 = (160)/(25)`

∴ For 80 students, we require
`6.4 \ chaperones`, however, we cannot use decimal for number of person, so we can round off the number to 6 chaperones on every 80 students.
