508/521 = ≈97.5%
Rounded to 2 decimal places.
A fraction like 508/521, or about 97.5%, could describe a school with nearly all students attending a special event. It might also represent a product’s success rate, the portion of a budget already completed, or the percentage of items that passed inspection.
You can picture 97.5% as almost the entire group, with only a very small part left out. For a quick estimate, imagine 100 squares with about 98 shaded; the unshaded two or three squares make the missing amount easier to notice.
A common mistake is to treat 97.5% as exactly 98% or even 100% when precision matters. That small difference can be important when the total is large, such as in quality control, survey results, or medical testing.
