Explanation:

Dimensional analysis uses the fact that any number can be multiplied by one without changing its value.

You want to convert hectometres to metres, so you multiply the hectometres by a conversion factor that equals one.

For example, you know that hecto  means "× 10², so  

1 hm = 100 m

If we divide each side by 1 hm, we get 1 = 100 m/1 hm.

If we divide each side by 100 m, we get 1 hm/100 m = 1.

So, we can use either (100 m/1 hm) or (1 hm/100 m) as a conversion factor, because each fraction equals one.

We choose the former, because it has the desired units on top.

The calculation becomes
