Question

3. Order the following lengths from shortest to longest.

a. 400 millimeters
b. 22 kilometers
c. 170 meters
d. 3.3 centimeters

Answer 1

Answer:
`d < a < c < b`

`3.3 cm < 400 mm < 170 m < 22 km`

Step-by-step explanation:

Firstly, let's convert these length to meters
`m`, in order to work with the same units:

a. 400 millimeters

`400 mm (1m)/(1000 mm)=0.4 m`

b. 22 kilometers

`22 km (1000m)/(1 km)=22000 m`

c. 170 meters

Here the lenght is already in meters

d. 3.3 centimeters

`3.3 cm (1m)/(100 cm)=0.033 m`

Now that we have all the lengths in meters, we can order them from shortest to longest:

`0.033 m < 0.4 m < 170 m < 22000 m`

or

`d < a < c < b`
