A fraction like 1/90, or about 1.11%, can show up when describing a small chance or a tiny portion of a group. For example, it could represent about one person out of every 90 customers choosing a certain option, or one defective item in a batch of 90.

To picture it quickly, imagine a large group split into 90 equal parts, with only one part selected. It is a little more than 1%, so you can think of it as roughly one out of every hundred, but slightly more common.

A common mistake is treating 1.11% as if it were 11%, which is ten times larger. The leading zero and decimal matter: 1.11% is a small amount, while 11% would be closer to one out of every nine.
