2/3 + 7/9 - 5/6 = 12/18 + 14/18 - 15/18 = 26/18 - 15/18 = 11/18
1 i 1/2 - 3/4 + 5/8 = 1 i 4/8 - 6/8 + 5/8 = 12/8 - 6/8 + 5/8 = 6/8 + 5/8 = 11/8 = 1 i 3/8
3/4 * 5/6 : 1/2 = 5/8 : 1/2 = 5/8 * 2 = 10/8 = 1 i 2/8 = 1 i 1/4
7/9 : 2/3 * 6/7 = 7/9 * 3/2 * 6/7 = 7/6 * 6/7 = 1
3 i 3/4 * 2 i 2/5 - 4 i 3/8 = 15/4 * 12/5 - 4 i 3/8 = 9 - 4 i 3/8 = 8 i 8/8 - 4 i 3/8 = 4 i 5/8
10 - 1 i 5/6 * 4 = 10 - 11/6 * 4 = 10 - 22/3 = 10 - 7 i 1/3 = 9 i 3/3 - 7 - 1/3 = 2 i 2/3
