A value like 10/15, or about 66.67%, can show up when 10 out of 15 people choose the same option in a survey. It could also describe finishing 10 of 15 tasks, attending 10 of 15 events, or getting 10 questions right on a quiz.

You can picture 10/15 as about two-thirds of a whole. A quick estimate is that 66.67% is a little more than half but not quite 70%, so shading roughly two sections out of every three gives a useful mental image.

One common mistake is treating 10/15 as if it were 10%, since the numerator is 10. The 15 in the denominator matters because it tells you the total number of parts, making the value about 66.67% rather than 10%.
