10/402 = ≈2.49%
Rounded to 2 decimal places.
A fraction like 10/402 could describe a small share of people in a survey, products in a shipment, or applications that meet a certain condition. In percentage terms, that is 2.49%, so it represents only a small portion of the whole.
To picture it quickly, imagine 10 selected items out of a group of about 400. You can estimate it as roughly 2.5 out of every 100, or about 1 out of every 40 people or objects.
A common mistake is to treat 2.49% as 0.249 or 24.9%, which is ten times larger. It is also easy to forget that the denominator, 402, represents the entire group being compared.
