(2 i 4/5 + 3 i 3/5) : 4/5 = 5 i 7/5 : 4/5 = 32/5 * 5/4 = 8
23 : ( 1 i 1/6 + 3/4) : 4 i 1/2 = 23 : (1 i 2/12 + 9/12) : 4 i 1/2 = 23 : 1 i 11/12 : 4 i 1/2 = 23 : 23/12 : 9/2 = 23 * 12/23 * 2/9 = 12 * 2/9 = 24/9 = 2 i 6/9 = 2 i 2/3
3/5 : (1 i 1/2 - 3/4) = 3/5 : (1 i 2/4 - 3/4) = 3/5 : (6/4 - 3/4) = 3/5 : 3/4 = 3/5 * 4/3 = 4/5
