15/522 = ≈2.87%
Rounded to 2 decimal places.
A fraction like 15/522 could describe a small share of people in a survey, products in a shipment, or days with a certain result over a longer period. In percentage terms, that is about 2.87%, so it represents only a small portion of the whole.
To picture it quickly, imagine dividing 522 items into about 100 equal groups: 15 items would be close to 3 items out of every 100. You can also estimate it as roughly 1 out of 35, which helps show that the value is uncommon but not extremely rare.
A common mistake is to read 15/522 as 15% because the numerator is 15. The denominator matters just as much, since the 15 is being compared with 522 total items rather than 100.
