Answer: [tex]d < a < c < b[/tex]
[tex]3.3 cm < 400 mm < 170 m < 22 km[/tex]
Explanation:
Firstly, let's convert these length to meters [tex]m[/tex], in order to work with the same units:
a. 400 millimeters
[tex]400 mm \frac{1m}{1000 mm}=0.4 m[/tex]
b. 22 kilometers
[tex]22 km \frac{1000m}{1 km}=22000 m[/tex]
c. 170 meters
Here the lenght is already in meters
d. 3.3 centimeters
[tex]3.3 cm \frac{1m}{100 cm}=0.033 m[/tex]
Now that we have all the lengths in meters, we can order them from shortest to longest:
[tex]0.033 m < 0.4 m < 170 m < 22000 m[/tex]
or
[tex]d < a < c < b[/tex]
