Marlon

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 drawing. What is the drawing's scale factor?


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

Result

M =  0.005
r =  1:200

Solution:

$a=8 \ m=8 \cdot \ 100 \ cm=800 \ cm \ \\ b=4 \ \text{cm} \ \\ \ \\ M=b/a=4/800=\dfrac{ 1 }{ 200 }=0.005$

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