21/304 = ≈6.91%
Rounded to 2 decimal places.
A fraction like 21/304 could describe a small share of a group, such as 21 students out of 304 surveyed choosing a particular answer. That works out to about 6.91%, which might represent a product return rate, a neighborhood recycling result, or the portion of website visitors who sign up.
To picture it quickly, imagine 304 dots with only 21 colored in. Since 7% is close to 6.91%, you can think of it as about 7 out of every 100 people, or roughly 1 person in 14.
A common mistake is to treat 21/304 as if it were 21%, because the numerator is 21. The denominator matters just as much: compared with a group of 304, 21 is a much smaller share than 21 out of 100.
