9/402 = ≈2.24%
Rounded to 2 decimal places.
A value like 9 out of 402 might show up in everyday life when 9 people in a group of 402 respond to a survey, report an issue, or qualify for a special result. That is a very small share, about 2.24%, so it suggests the event is uncommon.
To picture 9/402 quickly, imagine dividing 402 items into about 100 equal groups and finding that only a little more than 2 of those groups would contain the selected items. You can also remember that it is close to 2 out of every 100, but slightly higher.
A common mistake is to treat 9/402 as if it were 9.02% by focusing on the digits without considering the whole denominator. The 402 matters because the same numerator, 9, represents a much smaller percentage when it is compared with a large total.
