15/397 = ≈3.78%
Rounded to 2 decimal places.
A value like 15/397 might show up when 15 people out of 397 respond to a survey, experience an issue, or qualify for a program. That is about 3.78%, so it represents a small share of the whole group.
To picture it quickly, imagine a crowd of about 400 people with only 15 of them highlighted. It is close to 4%, or roughly 4 people out of every 100, which makes it easier to estimate at a glance.
A common mistake is to think 15/397 is close to 15%, because the numerator is 15. The denominator matters just as much: since 397 is much larger than 100, the fraction is less than 15% and is actually under 4%.
