The owner of the Slick Wheel Skate Park plans to build more jumps, so she wants to know what her customers are riding. Yesterday, 19 customers rode skateboards, 14 customers rode scooters, and 17 customers rode bikes.

key idea

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.

solution

To find the relative frequency of each type of campsite, first find the total number of campsites that were booked.

There were a total of 25 campsites booked. Write the relative frequency of each type of campsite as a fraction with a denominator of 25.

Stop-n-Go campsites
Campsites	RV	Tent	Pop-up
Frequency	9	11	5
Relative frequency	9 25	11 25	5 25

Now write each relative frequency as a percent. Start with the relative frequency of RV campsites,

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

100

The relative frequency of RV campsites is 36%. You can write the other relative frequencies as percents the same way.

Stop-n-Go campsites
Campsites	RV	Tent	Pop-up
Relative frequency	36%	44%	20%
