The scale of the drawing was 9 mm = 1 meter. What is the scale factor of the drawing

Answer 1

In order to answer this question we need to convert both lengths of measure to the same unit. It's best to use the smaller unit of measure to avoid needing to complicate things with decimals. In this case mm is the smaller unit of measure, so meters will need to be converted to millimeters. There are 1000 mm in a meter. So, the scale factor of the drawing was 9:1000.
