1/99 = ≈1.01%
Rounded to 2 decimal places.
A value like 1/99, or about 1.01%, can show up when something happens roughly once out of every hundred tries. For example, it might describe a very rare prize in a game, a small chance of a shipping error, or a tiny portion of a large group.
To picture it quickly, imagine 100 people standing in a line and only one person being selected. It is just a little more than 1%, so you can estimate it as about one out of every hundred.
A common mistake is treating 1/99 as exactly 1%, even though it is slightly larger. The difference is very small in everyday situations, but it can matter when the value is used repeatedly or across a large number of events.
