Question

There are 30 students in a class, including 16 boys. Write each ratio..

Answer 1

30 students in a class ; 16 are boys

Girls to boys : to find the amount of girls, simply subtract the student total with the boy total.

30 - 16 = 14 

Therefore there are 14 girls in the class

So, our ratio should be ~ 14 : 16

Girls to all students : 

Girls is 14 students is 30

Therefore the ratio to girls to all students is ~ 14 : 30

Boys to girls : Simply get the boys amount to the other side of the girls amount

Therefore the ratio of boys to girls is ~ 16 : 14

Boys to all students : Get the amount of boys and the amount of all students to the opposite side of each other.

Therefore the ratio of boys to all students is ~ 16 : 30
