1%2Acm%2F8km=x%2Acm%2F16km

When you set up your proportion, make sure that similar quatities are in the numerators and denominators. Here, the numerators are 1 centimeter and x centimeters, while the denominators are 8 kilometers and 16 kilometers.

Now cross-multiply and solve:

8x=1%2A16
x=2

And remembering that x was expressed in centimeters in the original equation, so the answer is 2 cm.
