Let x be the number of students in the locking class.
Since the ratio of students in the locking class to students in the breakdancing class is 3 to 2, we can write:
x / (30 + x) = 3 / 2
Cross multiplying, we get:
2x = 3(30 + x)
2x = 90 + 3x
90 = x
Therefore, there are 18 students in the locking class.
The answer is 18.
