The design of the microchip has the scale 40:1

⇒ I cm on the actual is represents 40 cm on the design

⇒ The scale is 40 cm : 1 cm


Find the actual length for 18 cm on design :

40 cm → 1 cm

1 cm → 1/40 cm

18 cm → 1/40 x 18 = 9/20 = 0.45 cm


Answer: The actual length is 0.45 cm

ramanav757: The answer is 9/20cm
