204/204 = 100%
A fraction like 204/204 appears when every item in a group is accounted for or completed. For example, if all 204 students submit a permission form, the school has received 100% of the forms.
You can picture it as a whole circle filled in completely, with nothing missing. A quick estimate is that the top and bottom numbers are identical, so the fraction represents one complete group.
A common mistake is thinking the large numbers make the fraction greater than 100%. When the numerator and denominator are the same, the value is exactly one whole, or 100%, no matter how large the numbers are.
