Answer 1

8/7 * 3 = 24/7 = 3 i 3/7
2 * 1 i 1/7 = 2 * 8/7 = 16/7 = 2 i 2/7
2 i 1/5 * 3 = 11/5 * 3 = 33/5 = 6 i 3/5
5 * 10 i 1/2 = 5 * 21/2 = 105/2 = 52 i 1/2
10 * 8 i 2/3 = 10 * 26/3 = 86 i 2/3
5 * 7/10 = 35/10 = 3 i 5/10 = 3 i 1/2
2/7 * 14 = 28/7 = 4
2/18 * 12 = 24/18 = 1 i 6/18 = 1 i 2/6
4 * 5 i 5/12 = 4 * 65/12 = 260/12 = 21 i 8/12 = 21 i 2/3
6 i 2/8 * 6 = 50/8 * 6 = 300/8 = 37 i 4/8 = 37 i 1/2
3 * 5 i 5/6 = 3 * 35/6 = 105/6 = 17 i 3/6 = 17 i 1/2
