Rounded to 2 decimal places.
A value of 90.91% might show up as a quiz score, like getting 20 out of 22 questions right. It can also describe how often something works, such as a device succeeding in 20 of 22 attempts.
To picture 20/22 quickly, imagine a bar that is almost completely filled, with just two small spaces left. It’s close to nine-tenths, so you can think of it as roughly 91%.
One common mix-up is treating 90.91% as exact when it’s a rounded value. Also, the fraction’s denominator matters: 20 out of 22 does not tell the same story as 20 out of a much larger total.
