A scale on which 1 cm represents 5 m has a representative fraction of

  • A.1/500
  • B.1/5
  • C.1/50
  • D.1/5000

Answer: A

Five metres is 500 centimetres, so the ratio of drawing length to actual length is one in five hundred. Converting both lengths to the same unit before forming the ratio is the step most often omitted in this calculation.
