The shrunk representative fraction is obtained by multiplying the original fraction by the

  • A.reciprocal of the shrinkage factor
  • B.square of the shrinkage factor
  • C.length of the scale constructed
  • D.shrinkage factor

Answer: D

Correct answer: shrinkage factor

The paper has contracted, so a given drawing length now represents a greater actual length than it did, and the representative fraction must be reduced accordingly. Multiplying by the factor does exactly that: a nominal 1/1000 with a factor of 0.975 becomes 0.975/1000, or about 1/1026 - a smaller fraction, not a larger one.
