801/801 = 100%
A fraction like 801/801 represents a complete amount, or 100%. You might see this when every seat in a theater is filled, every assignment in a set is finished, or all the items in an order have been delivered.
You can picture it as one whole circle shaded from edge to edge, with nothing missing. For a quick estimate, notice that the numerator and denominator are the same, which means the value is exactly one whole rather than just close to it.
A common mistake is thinking that a large denominator makes the fraction small. In this case, both numbers grow together, so 801/801 still means the entire amount, not 801 pieces out of some larger total.
