66/67 = ≈98.51%
Rounded to 2 decimal places.
A value like 66/67, or about 98.51%, can show up when nearly everything in a group meets a requirement. For example, a school might report that 66 of 67 students turned in an assignment, or a factory might produce 66 acceptable items out of 67.
You can picture 66/67 as one whole group with just 1 small piece missing. Since 1/67 is only about 1.5%, the fraction is very close to 100%, but still slightly less.
A common mistake is to treat 66/67 as exactly 100% because the difference is so small. It is also easy to confuse the missing 1 out of 67 with 1%, even though it is a little more than 1%.
