A 3:8 ratio has 11 parts (3+8). 33/11 = 3. Each
part = 3
3*3 = 9
3*8 = 24
9:24
Boys:girls
There are 9 boys.

Answer: There are 9 boys in the class.


Explanation:

Given : The total students in the class =33

The ratio of boys to girls is 3:8.

Let the number of boys be 3x and the number of girls be 8x, thus the total number of students =3x+8x=11x

According to the question, we have


11x=3\\\Rightarrow\ x=3

Therefore, the number of boys =
3x=3(3)=9

Hence, there are 9 boys in the class.
