Rounded to 2 decimal places.
A value like 52/78, or about 66.67%, might describe how many questions someone got right on a quiz or how much of a task is finished. It means the amount is a little more than half and close to two-thirds.
To picture it quickly, imagine a circle or chocolate bar split into three equal parts: this value is about two of those parts. That mental picture also helps you estimate that it is around 67 out of every 100.
One common point of confusion is treating 66.67% as exact, when it is a rounded value. The fraction 52/78 is exactly two-thirds, while its percentage continues with more decimal places beyond 66.67%.
