21/328 = ≈6.4%
Rounded to 2 decimal places.
A fraction like 21/328 can show up when 21 items out of a group of 328 meet some condition, such as defective products in a shipment or students who choose a certain activity. That portion is about 6.4%, so it represents a relatively small part of the whole.
To picture it quickly, imagine a group of 100 people: roughly 6 or 7 of them would match the same proportion. You can also think of 21 out of 328 as a little more than 1 out of every 16 people.
A common mistake is to treat 6.4% as if it means 6.4 items, even though the actual count here is 21 items. Another point of confusion is forgetting that the denominator, 328, represents the entire group, so changing the total would change the percentage.
