Rank the measurements in order from smallest to largest

Question

1.0 x 10^-5 m

2.0 x 10^-6 m

3.0 x 10^-7 m

4.0 x 10^3 mm

1.0m

Answer 1

Let us first convert 4.0x10³ mm to m so all measurements are in m (meters)

4.0x10³ mm x 1 m/1000 mm = 4.0 m

Ranking:

3.0x10^-7 m < 2.0x10^-6 m < 1.0x10^-5 m < 1.0 m < 4.0x10⁴ mm (4.0 m)
