We need to find the relative frequency of the eighth-graders who chose the fruit smoothies.

To find a relative frequency we need to divide the number of people from eight grade who chose fruit smoothies, shown in the following image:

Divide that number by the total number of people in eighth grade:

Thus, we get the following:


\text{relative frequency=}\frac{Number\text{ of eighth graders who want smoothies}}{\text{Total number of eighth graders}}

Substituting our values:


\text{relative frequency=}(17)/(250)

Solving the division:


\text{relative frequency =}0.068
