Question

In a scale drawing, 3 millimeters represents 17 meters. Exactly how many millimeters represents 55 meters?

Answer 1

Answer: Approximately 9.706 mm

Work Shown:

(3 mm)/(17 m) = (x mm)/(55 m)

3/17 = x/55

3*55 = 17*x

165 = 17x

17x = 165

x = 165/17

x = 9.706 approximately

Side note: I used the cross multiplication rule for the third step.
