1602/1603 = ≈99.94%
Rounded to 2 decimal places.
A value like 1602/1603 can describe something that is almost completely successful, such as a quality-control check where 1602 out of 1603 products pass inspection. It could also represent a very high delivery rate, attendance rate, or percentage of messages sent without errors: 99.94%.
To picture it quickly, imagine a group of 1,603 items with only one item missing or failing. Since the fraction is just one step below a whole, you can estimate it as nearly 100%, with a tiny gap of about 0.06 percentage points.
A common mistake is to call 99.94% exactly 100%, even though the difference can matter when the total number of items is large. Another point of confusion is thinking the fraction is 1602 parts out of 1602, when its denominator is 1603, so one part is still left out.
