A scale expressed as 1:50,000 is called

  • A.a representative fraction
  • B.a verbal statement of scale
  • C.a graphic or bar scale
  • D.a nominal reference scale

Answer: A

Correct answer: a representative fraction

A representative fraction states the scale as a pure ratio, so it is independent of units - one of anything on the map is 50,000 of the same thing on the ground, whether inches, centimetres or paces. That unit independence is its advantage over a verbal scale, and unlike a bar scale it does not survive photocopying at a different size.
