25%.
There are 12 circles. 3 of the 12 are shaded. That makes 3/12. Simplify it to 1/4. To convert fractions to percentages, the denominator must be 100. 4x25 gets you 100. Then multiply 1 by 25 too (to keep it even), and you get 25/100. 25/100 is 25%. As long as the denominator is 100, your numerator is the answer. Just put the percent sign in and that's your answer.
