A reducing scale is used when the object is

  • A.larger than the sheet it must be drawn on
  • B.smaller than can conveniently be drawn full size
  • C.of exactly the same size as the drawing sheet
  • D.of a size that cannot be measured at all

Answer: A

Correct answer: larger than the sheet it must be drawn on

A reducing scale is used when the object will not fit at full size - a building, a machine, a survey. An object too small to draw conveniently at full size calls for an enlarging scale instead, and the two are distinguished by whether the representative fraction is less than or greater than unity.
