9/20 = 45%
The fraction 9/20, or 45%, can show up in everyday situations such as a survey, a test score, or a sale discount. For example, if 9 out of 20 students prefer one activity, that group makes up 45% of the class.
A quick way to picture 9/20 is to imagine a strip divided into 20 equal parts, with 9 shaded. It is just under half, since half of 20 parts would be 10, so 45% is close to 50% but slightly less.
A common mistake is to think 9/20 means 9 fewer than 20, rather than 9 parts out of 20 equal parts. It is also easy to confuse 45% with 9%, even though the fraction represents nearly half of the whole.
