25% is 1/4.

If 12 is 1/4 of all the students in the class, that would mean that 12 x 4 = 48, which is the number of people in the class.

There are 48 people in the class.
 
Well, let's see, this is a stumper! How about realizing that 12 equals one quarter (25%) of the entire class. So, 4 times 12 ought to be it, no? The answer is 48.

25% can be converted to 1/4. Then set up a proportion.

12/x = 1/4 (On paper, it's easier to write this vertically.)

Then multiply diagonally. 12 x 4 = 48, then divide by 1. 48/1 = 48.

48 students.
