Question :

★In a class , there are 45 boys and 15 girls.find the ratio of:

(1) girls to boys

(2)boys to girls (3)boys to total number of students

Answer :

•Total number of Girls in the class = 15

•Total number of boys in the class = 45

•Total number of Students in the class = 45+15 = 60

1. Girls to Boys-

Total no. of girls : Total no. of boys

= 15:45

{Divide by 15}

= 1:3

2. Boys to Girls -

Total no. of boys : Total no. of girls

=45:15

{Divide by 15}

= 3:1

3.Boys to Total number of students

Boys : Total number of students

=45:60

{divide by 15}

=3:4

#Points to remember-

• Always try to simplify the ratio , as much as possible

• It can also be represented in the form of fraction
