According to the condition, there are 5 equal parts of female teachers and 3 equal parts of male teachers.
In all, there are 5 + 3 = 8 equal parts, and you can easily calculate the number of teachers in each part by dividing 40 by 8.
You will get = 5 persons in each part.
Hence, there are 5*5 = 25 female teachers and 5*3 = 15 male teachers.
There are other ways to solve this problem, but this one is the simplest.
