264/264 = 100%
The fraction 264/264 represents a complete amount, or 100%. You might see this when all 264 students in a school complete a survey, every item in a shipment arrives, or a phone battery is fully charged.
You can picture it as one whole circle, a completely filled progress bar, or every seat in a group being occupied. Since the top and bottom numbers are the same, you can quickly estimate that the value is the entire amount.
A common mistake is thinking that 264/264 must be a large value because the numbers look large. The size of the numbers does not matter here; because the numerator and denominator match, the fraction means one complete whole.
