.023 lies between

  • A..2 and .3
  • B.-.02 and -.03
  • C..03 and .02
  • D.-.03 and .02

Answer: C

.023 lies between .03 and .02.

Compare in thousandths: .023 is 23 thousandths, .02 is 20 thousandths and .03 is 30 thousandths, so

\[ 0.02 < 0.023 < 0.03 \]

.2 and .3 are ten times too large. The range -.02 to -.03 holds only negative numbers, so it cannot contain .023. The range -.03 to .02 stops at .02, and .023 is just above it. Writing every number with the same count of decimal places (.020, .023, .030) makes such comparisons easy.
