A value of 5/51, or 9.8%, could show up in a small survey, such as 5 people out of 51 choosing the same answer. It might also describe a small share of items in a batch, like 5 out of 51 products having a certain feature.

To picture it quickly, think of about 10 out of every 100—roughly one in ten. It’s just a little less than that, so you can estimate it as close to 10%.

A common mix-up is to focus only on the 5 and think the share is 5%. The 51 matters too: it’s the total group being counted.
