15/403 = ≈3.72%
Rounded to 2 decimal places.
A fraction like 15/403 could describe a small share of people in a survey, such as the number who choose a less common option. It might also represent a few defective products in a shipment or a small portion of students participating in an activity, equal to about 3.72%.
To picture it quickly, imagine 100 equally likely cases: this fraction is a little less than 4 out of every 100. You can also think of it as roughly 1 person in 27, which helps show that it is uncommon but not extremely rare.
A common mistake is to treat 15/403 as if it were 15/400 and assume the difference does not matter in every situation. That estimate is close, but the exact denominator still matters when the fraction is used for official reports, comparisons, or decisions.
