A value like 18/99, or about 18.18%, can show up when roughly 18 out of every 99 people, items, or responses meet a condition. For example, a survey might find that about this share of students prefer a certain lunch option, or that this portion of products in a shipment are a particular color.

To picture 18.18% quickly, think of it as a little less than one-fifth. Since one-fifth is 20%, you can imagine shading about 18 or 19 parts out of every 100.

A common mistake is treating 18/99 as if it were close to 18%, because the numerator is 18. The denominator matters too, and since 99 is just below 100, the value is slightly more than 18%, not exactly 18%.
