- 7/18 - (- 4 5/12 + 4/9) = - 7/18 - (- 53/12 + 4/9) = - 7/18 - (- 159/36 + 16/36) = - 7/18 - (- 143/36) = - 14/36 + 143/36 = 129/36 = 43/12 = 3 7/12
3/16 * (4/15) - 11/12 / 1 5/6) = 3/16 * (4/15) - 11/12 / 11/6) = 3/16 * (4/15 - 1/2) = 3/16 *(8/30 - 15/30) = 3/16 * (-7/30) = - 7/160
5/6 - (- 1 11/18 - 7/12) = 5/6 - (- 29/18 - 7/12) = 5/6 - (- 58/36 - 21/36) = 5/6 - (- 79/36) = 30/36 + 79/36 = 109/36 = 3 1/36
27/28 / 9/14 + 2 5/8 / (- 6/7) = 3/2 + 21/8 / (- 6/7) = 3/2 - 147/48 = 72/48 - 147/48 = 75/48 = 25/16 = 1 9/16
-7/9 - (2 5/15 - 11/20) = - 7/9 - (35/15 - 11/20) = - 7/9 - (140/60 - 33/60) =
-7/9 - 107/60 = - 420 / 540 - 963/540 = -1383 / 540 = - 2 303/540 =
- 2 101/180
