21/597 = ≈3.52%
Rounded to 2 decimal places.
A value like 21/597, or about 3.52%, could describe a small portion of people in a survey who chose a certain answer. It might also represent a few defective products in a large shipment or a small number of rainy days in a longer season.
To picture 3.52% quickly, think of about 3 or 4 items out of every 100. It is a little more than one out of 30, so it is noticeable but still a fairly small share.
A common mistake is to treat 3.52% as 3.52 whole items, even though a percentage describes part of a group. Another point of confusion is assuming that a small percentage always means an unimportant number; in a group of thousands, even 3.52% can include many people or items.
