Answer 1

For 135 students , the number of teacher requires is 9

Explanation:

Given as :

The number of teacher = 6

The number of student = 90

∵ For 90 students , the number of teacher requires = 6

So , For 1 student , the number of teacher requires =
`(6)/(90)`

=
`(1)/(15)`

∴ For 135 student , the number of teacher requires =
`(1)/(15)`×135

Or, For 135 student , the number of teacher requires =
`(135)/(15)`

So, For 135 student , the number of teacher requires = 9

Hence For 135 students , the number of teacher requires is 9 Answer
