Question

the ratio of teachers to pupil In a school is 1:5 how many teachers are in the school if the number of pupils is 100?

Answer 1

There are 20 teachers in a school with 100 pupils.

Explanation:

Given that the ratio of teachers to pupils in a school is 1:5, we can determine how many teachers are in a school with 100 pupils using a proportion:

1 teacher / 5 pupils = x teachers / 100 pupils

(1/5 = x/100) * 100

100/5 = x

20 = x

Therefore, there are 20 teachers in a school with 100 pupils.
