Part (a) · 1 mark

Arrange 0.501, 0.51, 0.5 and 0.55 in ascending order, smallest first.

  1. 1Compare the decimals digit by digit.
  2. 20.5 = 0.500, so it is smaller than 0.501.
  3. 30.501 < 0.510 (which is 0.51).
  4. 40.51 < 0.55.
  5. 5So the order is 0.5, 0.501, 0.51, 0.55

Answer0.5, 0.501, 0.51, 0.55
