total no. of students in the class = 32
let X be the no. of girls
let Y be the no. of boys
X + Y = 32
Given, X/Y = 1/4or Y = 4X
Therefore, X + 4X = 32
5X = 32
X = 32/5
let X be the no. of girls
let Y be the no. of boys
X + Y = 32
Given, X/Y = 1/4or Y = 4X
Therefore, X + 4X = 32
5X = 32
X = 32/5

I don't think that no. of girls will be fractional number. It must be natural number.
