Answer 1

75 - 48 i 2/7 = 74 i 7/7 - 48 i 2/7 = 26 i 5/7
26 i 2/3 + 9 i 5/9 = 26 i 6/9 + 9 i 5/9 = 35 i 11/9 = 36 i 2/9
4 i 2/5 * 5 i 10/11 = 22/5 * 65/11 = 26
16 : 5 i 1/3 = 16 * 3/16 = 48/16 = 3
7 * 3 i 1/14 = 7 * 43/14 = 301/14 = 21 i 7/14 = 21 i 1/7
10 i 1/2 - 2 i 2/3 = 10 i 3/6 - 2 i 4/6 = 9 i 9/6 - 2 i 4/6 = 7 i 3/6 = 7 i 1/2
2 i 2/3 : 5 i 2/6 = 8/3 * 6/32 = 2/4 = 1/2
