3. Order the following lengths from shortest to longest.

horrorfan [7]

Answer: $d < a < c < b$

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

Explanation:

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

a. 400 millimeters

$400 mm \frac{1m}{1000 mm}=0.4 m$

b. 22 kilometers

$22 km \frac{1000m}{1 km}=22000 m$

c. 170 meters

Here the lenght is already in meters

d. 3.3 centimeters

$3.3 cm \frac{1m}{100 cm}=0.033 m$

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

$0.033 m < 0.4 m < 170 m < 22000 m$

$d < a < c < b$
