Answer:

For 135 students , the number of teacher requires is 9

Step-by-step 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 = [tex]\frac{6}{90}[/tex]

                                                                                     = [tex]\frac{1}{15}[/tex]

∴   For 135 student , the number of teacher requires =  [tex]\frac{1}{15}[/tex]×135

Or, For 135 student , the number of teacher requires =  [tex]\frac{135}{15}[/tex]

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

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