A value like 9/399, or about 2.26%, might describe a small share of people in a survey who choose a particular answer. It could also represent a few defective products in a large shipment or a low chance of a rare event happening.

To picture it quickly, imagine 9 items highlighted in a group of 399, or roughly 2 out of every 100 items. Since 2.26% is close to 2%, it helps to think of it as about one-fiftieth of the total.

A common mistake is to read 2.26% as 2.26 rather than as a little more than two out of every hundred. Another point of confusion is assuming the fraction is exactly 2%, even though 9/399 is slightly higher.
