68/85 = 80%
A value of 80% might show up as a quiz score, a phone battery level, or the amount of a project that’s finished. It tells you that most of the whole is there, but a noticeable part is still missing.
To picture 80%, imagine a row of 10 equal boxes with 8 shaded in. You can also think of it as about four-fifths of something, which is close to “most, but not all.”
A common mix-up is treating 80% as if it means 80 out of any number of items. It means 80 out of every 100, so the actual count depends on the size of the whole.
