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 =
(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
