Ответ:
The number of boys in the class is 12
The number of girls in the class is 20
Step-by-step explanation:
Given as :
The ratio of boys to girls in school classroom = 3 : 5
The Total number of students in class = 32
Let The number of boys in class = 3 x
And The number of girls in class = 5 x
According to question
The Total number of students in class = The number of boys in class + The number of girls in class
Or, 3 x + 5 x = 32
Or, 8 x = 32
∴ x =
I.e x = 4
So, The number of boys in class = 3 x = 3 ×4 = 12
And The number of girls in class = 5 x = 5 ×4 = 20
Hence The number of boys in the class is 12
And The number of girls in the class is 20 Answer
