On a map of the United States, 24 centimeters represents 18 miles.
How many centimeters represent one mile?
We can set up the following proportion
[tex]\frac{x\operatorname{cm}}{1\: mi}=\frac{24\operatorname{cm}}{18\: mi}[/tex]Let us solve the equation for x.
[tex]\begin{gathered} x=\frac{24\operatorname{cm}}{18\: mi}\cdot1\: mi \\ x=\frac{4}{3}\operatorname{cm} \end{gathered}[/tex]Therefore, 4/3 cm represents one mile.
