109/3564 = ≈3.06%
Rounded to 2 decimal places.
A value like 109/3564, or about 3.06%, might describe a small share of people in a survey, a few defective items in a large shipment, or the chance of a rare event. It is useful whenever something happens to only a small portion of a much larger group.
To picture 3.06% quickly, think of about 3 out of every 100 items, or roughly 1 out of 33. That makes it clearly more than 1% but still a fairly small amount.
One common mistake is treating 3.06% as 0.306 when writing it as a decimal; the correct decimal form is 0.0306. Another point of confusion is assuming that a small percentage always means a small number, since 3.06% of a very large group can still be thousands of people or items.
