Question

I don’t want the answer to this just how to work it out. The required staff to student ratio is 2:15. If 340 people attended the excursion, how many teachers were there?? Thanks

Answer 1

40 teachers.

Explanation:

• The required staff to student ratio is 2:15
• 340 people attended the excursion.

We are to find the number of teachers (staff) who attended the excursion).

For every 2 staff, there are 15 students

The number of teachers who attended the excursion is
`(2)/(17)` × 340 = 40 teachers

The number of students who attended the excursion is
`(15)/(17)` × 340 = 300
