3/87 = ≈3.45%
Rounded to 2 decimal places.
A value like 3.45% might describe the share of people in a survey who chose a less common answer, or the small chance of a rare event. It can also show up as a defect rate, such as the portion of items in a large batch that have a problem.
To picture it quickly, think of a little more than 3 people out of every 100. It’s roughly 1 out of 29, so it represents a small but noticeable share.
One common mix-up is treating 3.45% as 3.45 whole units rather than a percentage of a larger amount. The actual number it represents depends on what total you’re measuring.
