69/72 as a percentage is 95.83%. This number tells you that the fraction is just a little short of a whole (or 100%). When you see it written this way, it’s easy to compare it with other values that are also given as percentages.
The fraction 69/72 can be reduced to 23/24, which is still a very large part of a whole. Because it’s so close to 1, it often shows up in situations where something is almost complete, like a project that’s nearly finished or a test score that’s just a few points shy of perfect.
Seeing 95.83% can help you quickly understand how good or how full something is without having to work with the original numbers. It’s a handy way to communicate that something is very high, but not quite at the maximum.
