Answer:
15
Step-by-step 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!
