Girls: 24
Boys: 16

First, multiply 2/5 by 40.
   2/5 X 40/1 = 80/5

Then, divide it.
   80 ÷ 5 = 16
*The answer will be the number of boys.

Subtract the number of boys by the total number of students which is 40.
   40 - 16 = 24
*The answer will be the number of girls.

Checking:
 24 + 16 = 40
 40 = 40
