Answers

  1. (a) \(\frac{ 5 }{ 9 }\)
    (b) \(\frac{ 65 }{ 99 }\)
  2. \(\frac{ 13 }{ 45 }\)
  3. \(\frac{ 4 }{ 27 }\)
  4. (a) \(0.\dot{ 7 }\)
    (b) \(0.\dot{ 6 }\dot{ 3 }\)
    (c) Let \(x = 0.\dot{9}\). Then \(10x = 9.\dot{9}\), so \(10x - x = 9\), giving \(9x = 9\) and \(x = 1\).
  5. (a) \(2\frac{ 82 }{ 99 }\)
    (b) \(\frac{ 280 }{ 99 }\)

  8. \(\frac{ 33 }{ 37 }\)
  9. (a) \(0.\dot{ 4 }\)
    (b) \(0.\dot{ 2 }\dot{ 7 }\)
    (c) Let \(x = 0.\dot{9}\). Then \(10x = 9.\dot{9}\), so \(10x - x = 9\), giving \(9x = 9\) and \(x = 1\).
  10. (a) \(2\frac{ 34 }{ 99 }\)
