The correct answer is 30%. Any percentage number out of 100 is the original number. If you're having trouble remembering this, just set up a proportion like you would for any other percentage problem. 30 / 100 = x / 100   In this proportion, we're trying to find the percent out of 100 that 30 divided into 100 is. This is represented by the variable x. 3000 = 100x   Cross-multiply 30 and 100. 30 = x   Divide. So, x, the percentage that 30 divided into 100 is out of 100, is 30, meaning that 30 is 30% of 100. Hope this helps!
