Answer:
Explanation:
In order to convert 6.7 hectometers to meters using dimensional analysis, you must use the ratio of hectometers to meters.
There are 100 meters in one hectometer, then you start setting the equality: 100 m = 1 hm.
Dividing both sides by 1 hm you get the fraction form of the ratio, with meters (m) in the numerator and hectometers (hm) in the denominator.

Since hm is in the numerator, when you multiply 6.7 hm by the unit ratio the hm will be canceled and the result will have only m:

Derived from a greek word meaning “Earth” in most cases it means “global” or relate to the Earth somehow
