5/40 = 12.5%
A value like 5/40, or 12.5%, can show up in everyday situations such as a sale, survey, or classroom group. For example, if 5 out of 40 students choose the same activity, that group makes up 12.5% of the class.
To picture 12.5% quickly, think of half of a quarter. It is a little more than one out of every ten, but much less than one out of every five.
A common mistake is thinking 12.5% means 12.5 out of 100 whole objects in every situation. The fraction 5/40 describes five items out of a group of 40, so the actual number of items depends on the total group size.
