640/655 = ≈97.71%
Rounded to 2 decimal places.
A value like 640/655, or about 97.71%, could describe a school attendance rate, a nearly full battery, or the share of products that passed inspection. It means that almost everything in the group meets the goal, with only a small number left out.
To picture it quickly, imagine 655 small squares with 640 colored in. The uncolored 15 squares make up just a little more than 2%, so the fraction is very close to 100% but not quite there.
A common mistake is to round 97.71% to 100% and forget that the remaining amount can still matter. In a large group, even a small gap from 100% may represent many people, items, or events.
