Question

The diagram below shows the percentage of people who like cats or dogs.16,800 people were asked, "Do you prefer cats or dogs?" How many people like dogs?

Answer 1

We can solve this question by using the rule of three. In this case we have

`\begin{gathered} 16800\rightarrow100 \\ x\rightarrow55 \end{gathered}`

Then the number of people who like dogs is

`((55)(16800))/(100)=(924000)/(100)=9240`

Therefore, 9240 people like dogs.
