63/72 = 87.5%
A value of 87.5% could describe a test score, a nearly full phone battery, or how much of a project is finished. It shows that most of the whole is there, but a small part is still missing.
A quick way to picture it is seven out of eight equal parts. That’s close to nine out of ten, but a little lower.
One common mix-up is treating 87.5% as exactly 90%. The difference may seem small, but it can matter when comparing scores, discounts, or progress.
