In mrs. nathan's class, there are 12 boys and 15 girls. what is the ratio of girls to boys in mrs. nathan's class? a. 1: 12 b. 5: 4 c. 12: 1 d. 4: 5

12:15

Both are divisible by 3.

12/3=4 15/3= 5

4:5 or "D"

Remember, the question said boys to girls, so it would be 4:5, NOT 5:4.

I hope this helps!
