Question

The ratio of boys to girls in a class is 5 to 7. If there are 36 students in the class, how many boys are there?

Answer 1

15

Explanation:

First, add up the boys and girls to find out how many total students are in the class. 7+5=12. The question wants us to find the number of boys in a 36-student class. To do this divide 36/12=3. There are three times more students in this class than in the 12-student class. Multiply 3 by 5 (boys in original class)= 15. There are 15 boys in the 36 student classroom. We can go further and Instead of doing the same thing to find the number of girls, we can subtract 36-15=21.

15 boys

*EXTRA*=21 girls

Hope this helps!

Answer 2

15 boys

Explanation:

5+7=12 36(students)/12= 3(groups) so 3*5(girls)=15 3*7(boys)=21
