Answer:
8
Step-by-step explanation:
Firstly, we can simplify the ratio of boys to girls to
1:2.
Then, to find out how many students each ratio represents, we add up 1 and 2 and to get 3(1+2=3)
By dividing
3
by the number of students, we can find how many students ONE ratio represents:
24
---- = 8
3
So ONE ratio is equal to 8
boys. Since our simplified ratio of boys to girls is
1:2.
already, we do not have to do further multiplying - the number of boys is simply 8.
For the girls, simply multiply 2 by 8 to get 16.
Check:
8 boys + 18 girls = 24 students.
