A value like 133/330, or about 40.3%, can show up when roughly four out of every ten people choose a certain option in a survey. It might also describe a test score, a discount, or the portion of a project that has been completed.

To picture 40.3% quickly, imagine a group of 10 equal parts with about 4 of them shaded. Since it is just a little more than 40%, you can estimate it as two-fifths.

A common mistake is treating 40.3% as the same as 40.3, even though the percent sign means “out of 100.” It is also easy to round it to 40% and forget that the extra 0.3 percentage points may matter in a large group.
