2/77 = ≈2.6%
Rounded to 2 decimal places.
A share like 2.6% might describe a small group in a survey, such as a few people out of a larger crowd choosing the same answer. It can also show up as a small chance of an event or a small portion of items with a defect.
To picture 2/77, imagine about 2 or 3 people in a group of 77. It is a little more than 2 out of every 100, so it is a small but noticeable share.
A common point of confusion is treating 2.6% as exact. It is an estimate, so the precise percentage for 2/77 is slightly different.
