5/80 = 6.25%
A value like 5/80, or 6.25%, might show up in a survey where 5 out of 80 people choose the same answer. It could also describe a small share of items in a batch, such as a few products with a certain feature.
To picture it quickly, think of a little more than 6 people out of every 100, or about 1 part in 16. That makes it clear that the amount is small, but not quite as tiny as 5%.
A common mix-up is reading 6.25% as 6.25 out of 10, when it means 6.25 out of 100. It’s also easy to confuse it with 0.625%, which is ten times smaller.
