Question

Representative fraction is .

• A. unitless
• B. measured in cm
• C. measured in inches
• D. measured in km

Answer 1

The correct option is A unitless

A representative fraction is the ratio of the distance between two points on the map to the distance between them on the ground. The ratio remains the same for any unit of distance chosen and is a unitless quantity. The representative fraction ensures that no matter what size you print the map in, you will inevitably arrive at the same measured distance.
