A share of 9/27, or about 33.33%, can show up when one out of every three items in a group has a certain feature. For example, if 9 of 27 students ride the bus, about a third of the class does.
A quick way to picture 9/27 is to think of a group split into three equal parts, with one part shaded. Since it is close to one-third, you can estimate it as a little more than 33% without needing an exact value.
A common mix-up is to read 33.33% as exactly one-third in every situation. It is a rounded percentage, so it is very close to one-third but not perfectly exact.
