18/30 = 60%
A value like 18/30, or 60%, can show up in everyday situations such as getting 60% of the questions right on a quiz. It might also describe a sale, a survey result, or how full a bus, theater, or sports stadium is.
To picture 18/30 quickly, imagine 30 equal spots with 18 filled in. That is a little more than half, since half of 30 would be 15, so you can estimate it as about three-fifths of the whole.
A common mistake is thinking 60% means 60 out of 100 items only. Percent means “out of 100,” but the same amount can be represented by different fractions, including 18/30, as long as they describe the same portion.
