78/100 = 78%
A value like 78% might show up as a test score, a phone battery level, or the share of people who prefer one option in a survey. It tells you that something is true or complete most of the time, but not all the time.
To picture 78%, imagine a grid with 100 small squares and about 78 of them shaded. You can also think of it as a little less than four out of every five, which is a quick way to estimate it.
One common mix-up is treating 78% as if it means 78 whole items, no matter the total. It means 78 out of 100, so the actual number depends on what the percentage is being compared with.
