27/54 as a percentage is 50.00%. This fraction reduces to 1/2, which is exactly half of a whole. Because we round to two decimal places, the answer appears as 50.00% instead of just 50%.
Seeing a value like 50.00% is useful when you need to compare parts of a group. For example, if you have 54 students and 27 of them pass a test, you can say that 50.00% of the class succeeded.
Writing the percentage with two decimal places keeps the format consistent, especially in tables or reports where other percentages might have more detail. It’s a clean, professional way to show that exactly half of the whole is being represented.
