801/802 = ≈99.88%
Rounded to 2 decimal places.
A value like 801/802, or about 99.88%, can describe everyday situations where almost everything succeeds or is included. For example, it could represent a reliable computer system, nearly all packages delivered correctly, or a very high attendance rate.
To picture it quickly, imagine 802 small squares with 801 shaded in. Only one square would remain unshaded, so the amount is just a tiny bit less than 100%.
A common mistake is to treat 99.88% as exactly 100%, especially when rounding to the nearest whole percent. That small difference may not matter for a single item, but it can become important when the value is applied to thousands of items or repeated many times.
