A value like 91/90 can show up when something is slightly more than a full amount, such as using 101.11% of a monthly budget or completing 101.11% of a project goal. It can also describe a measurement that is just over the expected target, like filling a container a little past its one-unit mark.

A common mistake is treating 91/90 as less than one because 91 looks smaller than 90 at a glance, even though it is actually larger. Another point of confusion is rounding 101.11% to 101%, which can hide the small extra amount when precise measurements matter.
