12/397 = ≈3.02%
Rounded to 2 decimal places.
A value like 12/397, or about 3.02%, could describe a small portion of a large group, such as 12 students out of 397 people at an event. It might also represent a low rate of defective products, survey responses, or customers choosing a particular option.
To picture it quickly, think of about 3 people out of every 100. Since 12 out of 397 is just over 3 out of 100, it is a little more than one person in 33.
A common mistake is to treat 3.02% as 3.02 people, even though percentages describe part of a group rather than a fixed number of people. The actual number represented depends on the total, so 3.02% of 397 is 12, but 3.02% of a different total will give a different amount.
