Explicație pas cu pas:
(a)
1/18 + ²⁾1/9 + ³⁾1/6 =
1/18 + 2/18 + 3/18 =
(1 + 2 + 3)/18 =
6/18 =
3/9

(b)
7/36 - ²⁾1/18 + ⁹⁾3/4 =
7/36 - 2/36 + 27/36 =
(7 - 2 + 27)/36 =
32/36 =
8/9
(c)
²⁾37/18 -⁹⁾3/4 - ⁶⁾5/6 =
74/36 - 27/36 - 30/36 =
(74 - 27 - 30)/36 =
17/36
(d)
11/18 - ²⁾4/9 + ³⁾5/6 - ⁶⁾1/3 =
11/18 - 8/18 + 15/18 - 6/18 =
(11 - 8 + 15 - 6)/18 =
12/18 =
