Answer:
16 girls in the class
14 boys in the class
Step-by-step explanation:
Because of the ratio of 7:8, I added 7+8.
7+8= 15
30 (the number of students in the class) divided by 15 (the sum of the ratio)
30/15= 2
I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.
Hope this helps!

Answer:
There are 406 students in the school
Step-by-step explanation:
Let the number of students in the school be x
The total ratio is 11 + 3 = 14
The ratio that buys lunch is represented by 3
So, we have it that;
3/14 * x = 87
3x = (14 * 87)
x = (14 * 87)/3
x = 406
