10/604 = ≈1.66%
Rounded to 2 decimal places.
The fraction 10/604 represents a small share of a larger group, such as 10 defective items out of 604 products inspected or 10 late arrivals among 604 total deliveries. In percentage terms, that is about 1.66%, so it describes something that happens only occasionally.
To picture it quickly, imagine 100 people in a room: fewer than 2 people would represent a similar share. You can also estimate it as roughly 1 out of every 60 people or items, which makes the size easier to understand.
A common mistake is to treat 1.66% as if it were 1.66, or as 1.66 out of 100 whole units without noticing that it is less than 2 out of 100. It is also easy to assume the fraction is exactly 1.66%, even though the percentage is rounded.
