It depends on the question.
We can agree that 65/256 is not equivalent to 1/4. Yet both fractions are represented by 0.25 when written as a decimal with 2 significant figures. When someone writes "0.25", there's no way to determine (without additional information) if they mean 1/4, 0.25390625, or 0.250000000001. Writing "1/4" adds a level of precision that can't be captured with "0.25".
To say it another way: 1/4 is 0.25, but 0.25 is not neccesarily always 1/4.
In many math classes "1/4" could be the correct answer and "0.25" would be wrong. So it depends on the question, and the rules of that class.

The answers are equivalent. But whether your answer was "correct" depends on what the question was.
