13/604 = ≈2.15%
Rounded to 2 decimal places.
A value like 13/604, or about 2.15%, could describe a small share of people in a survey, products in a shipment with a defect, or days in a year when a rare event happens. It is large enough to notice but still represents only a small minority.
To picture 2.15% quickly, imagine a group of about 600 items with only around 13 highlighted. You can also think of it as roughly 2 out of every 100, with a tiny bit extra.
A common mistake is to treat 2.15% as 2.15 whole units instead of a portion of the total. The fraction means 13 parts out of 604 equal parts, so the total number being measured matters.
