A value like 89.47% might describe how often a bus arrives on time, how much of a class passed a quiz, or how full a phone’s battery is. It means the result is close to nine out of every ten.

To picture it quickly, imagine 100 small squares with about 89 shaded in and a little less than half of one more. You can also think of it as just under 90%, which is easy to compare with familiar benchmarks.

A common mix-up is treating 89.47% as the same as 89.47 out of 10; the percent sign means “out of 100.” It’s also an approximate value, so the original fraction may not match that decimal exactly.
