508/518 = ≈98.07%
Rounded to 2 decimal places.
A value like 508/518, or about 98.07%, can describe a very high success rate in everyday life. For example, it might represent 508 correct answers out of 518, 508 working products in a shipment, or nearly all customers completing a survey.
To picture it quickly, imagine 100 items lined up with only about 2 missing or unsuccessful. Since 98.07% is just over 98%, it is much closer to 100% than to 95%.
A common mistake is treating 98.07% as exactly 98% or exactly 100%. The small difference matters when the total is large, because about 1.93% of 518 is still around 10 items.
