If there are 5 boys in 12 person class then there are 12-5 = 7 girls

ratio of boys to girls would be 5:7

ratio of girls to all students would then be 7:12

Well, since there are 5 boys of 12 students, we can subtract the total amount of students by the amount of boys to find the girls:

12 - 5 = 7.

Now that we know the amount of girls and boys, the ratio of boys to girls is:

a) 5 : 7.

And girls to all students is:

b) 7 : 12
