59/80 = 73.75%
A value like 59/80, or 73.75%, could describe a student answering 59 out of 80 questions correctly on a test. It might also represent finishing about three-quarters of a project, using most of a phone’s battery, or having 59 successful results out of 80 attempts.
To picture it quickly, imagine a bar divided into 80 equal parts with 59 shaded, leaving 21 parts unshaded. It is a little less than three-quarters, since three-quarters of 80 would be 60, so 59/80 is just 1/80 below 75%.
A common mistake is to round 73.75% to 74% or 75% and then treat the rounded value as exact. Rounding can be useful for a quick estimate, but the original value is slightly below 75%, not exactly three-quarters.
