Answer 2

The percentage of boys students in Jamie's class is 20 %

Explanation:

Given as :

The total number of boys in the Jamie's class =
`(1)/(5)` of the total student

Let the total number of student's in the class = x

So, The number of boys =
`(1)/(5)` × x

I.e The number of boys =
`(x)/(5)`

So , in percentage the number of boys students in class =
`(\textrm Total number of boy student)/(\textrm Total number of students)` × 100

OR, % boys students =
`((x)/(5))/(x)` × 100

or, % boys students =
`(100)/(5)`

∴ % boys students = 20

Hence The percentage of boys students in Jamie's class is 20 % . Answer
