The relative frequency of a category is the ratio of the number in that category to the total number.

Relative frequency =

number in a category

total number

Relative frequencies are often written as percents.

To find the relative frequency of each transportation method, first find the total number of friends Fred asked.

Fred asked a total of 20 friends. Write the relative frequency of each transportation method as a fraction with a denominator of 20.

Now write each relative frequency as a percent. Start with the relative frequency of taking the bus,

Since a percent tells you a part out of 100, write an equivalent fraction with a denominator of 100.

100

The relative frequency of taking the bus is 50%. You can write the other relative frequencies as percents the same way.

Transportation method	Bus	Walk	Bike	Car
Relative frequency	50%	15%	10%	25%
