81/83 = ≈97.59%
Rounded to 2 decimal places.
A value of 97.59% might describe how often a bus arrives on time or how many questions someone gets right on a test. It means the result is very close to perfect, with only a small amount left over.
To picture it quickly, imagine a grid of 100 squares with almost all of them filled in. You could also think of it as just a little less than 98 out of 100.
One common mix-up is treating 97.59% as exactly 98%, even though rounding changes the value slightly. That difference may not matter for a rough estimate, but it can matter when accuracy is important.
