A value like 30/90, or about 33.33%, can show up when a third of a group chooses the same option in a poll. You might also see a similar share when tracking how much of a monthly goal you’ve completed.

A quick way to picture it is as one part out of three equal parts. If you imagine a circle or a row of 90 items split into three equal groups, 30 items fill one group.

One common point of confusion is that 33.33% is an approximation, not the exact value of one third. Rounding can make the displayed percentage look slightly different, especially when several rounded amounts are added together.
