45 i 2/9 + 124 i 5/6 = 45 i 4/18 + 124 i 15/18 = 169 i 19/18 = 170 i 1/18
12 - 1 i 5/12 = 11 i 12/12 - 1 i 5/12 = 10 i 7/12
128 i 5/8 - 125 i 1/4 = 128 i 5/8 - 125 i 2/8 = 3 i 3/8
8 i 1/3 * 4 i 4/5 = 25/3 * 24/5 = 40
5 i 1/3 : 9 = 16/3 * 1/9 = 16/27
7 i 1/5 : 1 i 3/15 = 36/5 : 18/15 = 36/5 * 15/18 = 6
1 i 5/6 - 1/6 * 1 i 1/2 = 1 i 5/6 - 1/6 * 3/2 = 1 i 5/6 - 1/4 = 1 i 10/12 - 3/12 = 1 i 7/12
(4 i 1/6 - 3 i 5/7) : 19 = (4 i 7/42 - 3 i 30/42) : 19 = (3 i 49/42 - 3 i 30/42) : 19 = 19/42 * 1/19 = 1/42
(4/5 - 1/2)³ = (8/10 - 5/10)³ = 3/10³ = 27/1000
