Make proportion.

30/240 = x/100

240x = 3000

x = 3000/240

x = 12.5%

The words "of" and "is" have specific meanings in this sort of math problem.

* Of* indicates multiplication;

So your word problem becomes ? % (times) 240 (equals) 30

Or 240*? = 30 or ? = 30/240 = 1/8 and 1/8 equals .125

Then convert .125 to a percent:

.125*100 = 12.5%
