Which scale will produce the smallest drawing?
a) 1cm: 5m
b) 1mm: 50m
c) 5cm: 10m
d) 10cm: 25 m

The scale that will produce the smallest drawing would be b) 1mm:50m.

First, I converted all the measurements to centimeters:

a) 1cm:500cm
b) 0.01cm:5000cm
c) 5cm:1000cm
d) 10cm:2500cm

Then, you divide the scales:

a) 0.002
b) 0.000002
c) 0.005
d) 0.004

B is the smallest number, meaning it will be the smallest scale.
