Total students= Z
no of boys = X
Hence
no of girls = Z-X
The part of the class that is composed of girls=( Z-X)/Z
= Z/Z- X/Z
= 1-X/Z
c) 1- X/Z is composed of girls in a class
no of boys = X
Hence
no of girls = Z-X
The part of the class that is composed of girls=( Z-X)/Z
= Z/Z- X/Z
= 1-X/Z
c) 1- X/Z is composed of girls in a class
