Question

Which of the following is not equal to 0.1 centimeters? 0.000001 kilometers (km) 0.001 meters (m) 10 millimeters (mm) 1000 micrometers (µm)

Answer 1

Which of the following given measurement are not equal to 0.1 centimeters:
first choice = 0.000001 kilometers
=> 0.1 cm = 1e-6 km
Second choice = 0.001 meters
=> 0.1 cm = 0.001 meters
third choice = 10 millimeters
=> 0.1 cm = 1 millimeter
Fourth choice = 1000 micrometer
=> 0.1 cm = 1 000 micrometer
Thus the not equal that we are looking for is the millimeter. Because 0.1 centimeter is equals to 1 millimeter and not 10.

Answer 2

Answer: 10 millimeters (mm)

Step-by-step explanation:

The given units are used to measure length.

By metric conversion:

1.
`1cm=10^(-5)km`

Thus
`0.1cm=(10^(-5))/(1)* 0.1=0.000001km=10^(-6)km`

2.
`1cm=0.01m`

Thus
`0.1cm=(0.01)/(1)* 0.1=0.001m=10^(-3)m`

3.
`1cm=10mm`

Thus
`0.1cm=(10)/(1)* 0.1=1mm`

4.
`1cm=10000\mu m`

Thus
`0.1cm=(10000)/(1)* 0.1=1000\mu m`
