answer:

The scale factor of the drawing can be determined by comparing the units of measurement in the drawing to the actual units.

In this case, the scale of the drawing is 5 millimeters = 4 meters. To find the scale factor, we need to express this as a fraction where the numerator represents the units in the drawing and the denominator represents the actual units.

Since 5 millimeters represents 4 meters, the scale factor can be written as:

5 mm / 4 m

To simplify this fraction, we need to convert millimeters to meters. There are 1000 millimeters in 1 meter, so we divide the numerator and denominator by 1000:

(5 mm / 4 m) / (1000 mm / 1 m) = 5/4000

Therefore, the scale factor of the drawing is 5/4000.
