1/98 = ≈1.02%
Rounded to 2 decimal places.
A value like 1/98 can show up when about one person out of every 98 experiences something, such as a rare side effect, a small survey response, or an occasional equipment problem. In percentage terms, that is about 1.02%, so it describes something uncommon but not impossible.
To picture 1/98 quickly, imagine a group of 100 people and select about one person. It is slightly more than 1%, so you can estimate it as roughly one out of every hundred.
A common mistake is treating 1/98 as exactly 1%, even though it is a little larger. Another point of confusion is assuming that one person in every group of 98 must be affected; the fraction describes an average rate, not a guarantee for every group.
