QUESTION :
In a class of 40, the ratio of boys to girls is 3:5. How many are girls? How many are boys?
ANSWER :
Let the no. of boys and girls be 3x and 5x.
Total no. of students = 40
3x + 5x = 40
8x = 40
x = 40/8
x = 5
Therefore,
no. of boys = 3x = 3(5) = 15
no. of girls = 5x = 5(5) = 25
FINAL ANSWER : 15 boys, 25 girls
