82/100 = 82%
A score of 82% might show up on a test, a phone battery, or a weather forecast. It usually means something is doing pretty well, though the exact meaning depends on what’s being measured.
Picture 100 small squares, with 82 shaded in and 18 left blank. For a quick estimate, think of it as just a little more than four-fifths, since four-fifths is 80%.
A common mix-up is thinking 82% always means 82 items. It means 82 out of every 100, so the number of items depends on the total.
