60/100 = 30/x
60x = 3000
60x/60 = 3000/60
x = 50
There are 50 students.

Let n = total number of students.
It was said that 60% of n are girls, which is according to the problem, equal to 30. Thus,
60% * n = 30
Note that 60% is also equal to 0.6 in decimal form:
0.6 * n = 30
n = 30/0.6
n = 50 students
