The solutions of (a), (b) and (c) are as follows:

(a)

  • 4/5, -3/2, 0.25, 2/-3, -6/-5
  • 0.8, -1.5, 0.25, -0.67, 1.2
  • Therefore, the ascending order of the above is,
  • -1.5, -0.67, 0.25, 0.8, 1.2
  • The ascending order is -3/2, 2/-3, 0.25, 4/5, -6/-5

(b)

  • 14/15 + 11/12 + (-5/9)
  • taking the lcm of 15, 12 and 9, we have,
  • 180 is the lcm of 15, 12 and 9, so we get,
  • = [168 + 165 - 100] / 180
  • = 233/180
  • = (180 + 50)/180
  • The result in mixed fraction is 1 50/180 = 1 \frac{50}{180}

(c)

  • [(4/5 × 8/20) + 9/25] - 11/25
  • = [(4/5 × 2/5) + 9/25] - 11/25
  • = [(8/25) + 9/25] - 11/25
  • = 17/25 - 11/25
  • = (17 - 11)/25
  • = 6/25
