9/266 = ≈3.38%
Rounded to 2 decimal places.
A value like 9/266, or about 3.38%, could describe a small share of people in a survey, a few defective items in a large shipment, or a small number of rainy days in a season. It is the kind of percentage that shows up when only a handful of cases occur out of several hundred.
To picture it quickly, imagine dividing 266 objects into 100 equal groups of about 2.66 objects each, then selecting 9 of them. You can also estimate it as a little more than 3 out of every 100, which makes it clear that the amount is small but not extremely rare.
A common mistake is to treat 9/266 as if it were close to 9%, simply because the numerator is 9. The denominator matters just as much: 9 out of 266 is far smaller than 9 out of 100.
