Grace measured an apartment and made a scale drawing. The scale of the drawing was 3 millimeters = 1 meter. What scale factor does the drawing use?
Simplify your answer and write it as a fraction.
The scale of the drawing is 3 millimeters = 1 meter, which can be written as 3/1 millimeters = 1 meter.
To find the scale factor, we need to convert the units to the same type. Since there are 1000 millimeters in a meter, we can rewrite the scale as 3/1 * 1000/1 = 3000/1.
Therefore, the scale factor of the drawing is 3000/1.
