Answer: 16 of the students are girls.

Step-by-step explanation:

3/5 = boys —> 60% of students.

2/5 = girls —> 40% of students.

40% = 0.4

G = 40 * 0.4

G = 16

Given,
Ratio of boys to girls = 3:5
Let the number of boys = 3x
Let the number of girls = 5x
Also given, total number of students in class = 40
So, 3x +5x = 40
8x = 40
x = 40/8
x = 5
Therefore, number of girls in the class = 5(5) = 25
Number of boys in the class = 3(5) = 15
