3/249 = ≈1.2%
Rounded to 2 decimal places.
A value like 3/249, or about 1.2%, can show up when only a few items in a large group have a certain feature. For example, 3 damaged products out of 249 shipments would represent a very small failure rate.
To picture it quickly, imagine 249 people standing in a room and only 3 of them stepping forward. It is roughly 1 person out of every 80, so you can think of it as just over one person in a group of 100.
A common mistake is to treat 1.2% as if it were 12%, which is ten times larger. The decimal point matters: 1.2% is a little more than 1%, not more than 10%.
