10/397 = ≈2.52%
Rounded to 2 decimal places.
A value like 10/397 can show up when 10 people out of a group of 397 respond to a survey, report an issue, or qualify for a special result. In percentage terms, that is about 2.52%, so it describes a small portion of the whole group.
To picture 10/397 quickly, imagine 397 dots with only 10 of them marked; the marked dots would be spread out very thinly. You can also estimate it as roughly 2 or 3 out of every 100, which helps show that it is well below one-twentieth.
A common mistake is to treat 10/397 as if it were close to 10%, simply because the numerator is 10. The denominator matters just as much, and since 397 is much larger than 100, the actual share is only about 2.52%.
