Calculate the KFC restaurants to the total restaurants ratio as a decimal to the thousandths place and write ameaningful sentence. Is this part-to-part or part-to-whole?

Answer 1

A. To compute the ratio of Subway restaurants to McDonald's restaurants, we divide the number of Subway restaurants (25,549) by the number of McDonald's restaurants (14,146) :

`\begin{gathered} r=\frac{\#\text{Subway}}{\#McDonald^(\prime)s} \\ r=(25,549)/(14,146) \\ r=1.806 \end{gathered}`

• The ratio of Subway restaurants to McDonald's restaurants to the thousandths place is 1.806.

,

• This is a part-to-part ratio because this ratio is relating the number of two franchises of restaurants.

B. To compute the ratio of KFC restaurants to the total of restaurants, we divide the number of KFC restaurants (22,621) by the total number of restaurants (80,747):

`\begin{gathered} r=\frac{\#\text{KFC}}{\#\text{Total}} \\ r=(22,621)/(80,747) \\ r=0.280 \end{gathered}`

• The ratio of KFC restaurants to the thousandths place is 0.280.

,

• This is a part-to-whole ratio because this ratio is relating the number of restaurants of a franchise to the total number of restaurants.
