The number of girls in the class can be calculated using the given information.
Let's assume the number of boys in the class is x.
According to the given information, the number of girls is 9 more than the number of boys. So, the number of girls is x + 9.
The total number of students in the class is 39. So, the sum of boys and girls should be equal to 39:
x + (x + 9) = 39
2x + 9 = 39
2x = 30
x = 15
Therefore, the number of boys in the class is 15.
Now, the number of girls in the class is x + 9 = 15 + 9 = 24.
So, there are 24 girls in the class.
