Marlon drew a scale drawing of a summer camp. In real life, the sand volleyball court is 8 meters wide. It is 4 centimeters wide in the picture. What is the drawing's scale factor?


Simplify your answer and write it as a ratio, using a colon.

Correct answer:

M =  0.005
r =  1:200

Step-by-step explanation:

$$\begin{gathered} a=8\text{m}\to \text{cm}=8\cdot 100\text{cm}=800\text{cm} \\ b=4\text{cm} \\ M=b/a=4/800=\frac{1}{200}=0.005 \end{gathered}$$

$r=M=0.005=\frac{1}{200}=1:200$
