84/97 = ≈86.6%
Rounded to 2 decimal places.
A value like 86.6% could describe a student getting 84 questions right on a 97-question quiz. It could also show how much of a task is finished or how often something succeeds.
To picture 84/97 quickly, imagine filling about 87 spots in a row of 100. That makes it clear the value is a little less than nine-tenths.
One common mistake is to treat 84/97 as the same as 84%. The 84 is the number of parts you have, while 97 is the total those parts are out of.
