Explanation:

Step1: Convert units to same system

We know that 1 meter = 1000 millimeters. The drawing has 3 millimeters representing 1000 millimeters (1 meter) in real life.

Step2: Determine scale factor

Scale factor is (drawing length)/(actual length) = $\frac{3}{1000}$ (since 3 mm on drawing corresponds to 1000 mm in real).

Answer:

$\frac{3}{1000}$
