12/80 = 15%
A value like 15% can show up as a discount on a jacket, a tip at a restaurant, or the share of students who chose a certain answer. It describes a portion of a whole, not an amount by itself.
To picture 12/80, imagine 80 small squares with 12 shaded in. That’s a little less than one-sixth of the squares, so it’s clearly less than a quarter.
A common mix-up is treating 15% as 15 whole items, even when the total is much larger or smaller. The percentage tells you the share of the total, so the number of items depends on what the whole represents.
