59/60 expressed as a percentage is 98.33%. This value shows how close the fraction is to a whole number when viewed as part of 100.
Because it is just a little under 100%, the fraction can be used to describe situations where something is almost complete, such as a test score of 59 out of 60 points. It’s a handy way to see how high the proportion really is without dealing with the fraction itself.
The number is rounded to two decimal places, so the exact decimal would be a tiny bit higher, but 98.33% is accurate enough for everyday use.
