12/20 = 60%
A value like this might show up in a survey, such as when 12 out of 20 students prefer a certain school lunch. It can also describe a sale, a test score, or how much of a task is finished.
A quick way to picture 60% is to imagine a 10-by-10 grid with 60 squares shaded. You can also think of it as a little more than half, since half is 50%.
One common mix-up is treating 60% as if it means 60 out of 20. It means 60 out of every 100, while 12 out of 20 is the fraction that represents the same share.
