Given:
[tex]\frac{8\frac{1}{2}\text{ pizzas}}{5\text{ salads}}=\frac{?}{10\text{ salads}}[/tex]This means that 5 salads are needed for 8½ pizzas.
To find the missing value, cross multiply.
Thus , we have:
Let x represent the missing value
[tex]\begin{gathered} \frac{8\frac{1}{2}\text{ }}{5\text{ }}=\frac{x}{10\text{ }} \\ \\ \text{Cross multiply:} \\ 10(8\frac{1}{2})=5x \\ \\ 85\text{ = 5x} \\ \end{gathered}[/tex]Divide both sides by 5:
[tex]\begin{gathered} \frac{85}{5}=\frac{5x}{5} \\ \\ 17\text{ = x} \end{gathered}[/tex]Therefore, we have:
[tex]\frac{8\frac{1}{2}\text{ pizzas}}{5\text{ salads}}=\frac{17\text{ pizzas}}{10\text{ salads}}[/tex]ANSWER:
17 pizzas
