Answer 1

4/9 : 6/7=4/9 * 7/6 = 28/54 = 14/27
2 i 3/5 : 13/20= 13/5 * 20/13 = 4
1 i 1/3 : 16/21= 4/3 * 21/16 = 7/4 = 1 3/4
3 i 2/7 : 2 i 1/2= 23/7 : 5/2 = 23/7 * 2/5 = 46/35 = 1 11/35
5 i 4/5 : 2 i 1/10=29/5 : 21/10= 29/5 * 10/21 = 58/21 = 2 16/21
7 i 3/4 : 1 i 5/6=31/4 : 11/6 = 31/4 * 6/11 = 93/22 = 4 5/22
10 i 3/10 : 2 i 1/20= 103/10 : 41/20 = 103/10 * 20/41 = 206/41 = 5 1/41
2 i 3/7 : 1 i 3/14=17/7 : 17/14 = 17/7 * 14/17 = 2
5 i 1/5 : 2 i 2/15= 26/5 : 32/15 = 26/5 * 15/32 = 13 * 3/16 = 39/16 = 2  7/16
4 i 2/3 : 7 i 1/6= 14/3 : 43/6 = 14/3 * 6/43 = 14*2/43 = 28/43
3 i 1/9 : 1 i 1/6=28/9 : 7/6 = 28/9 * 6/7 = 4/3 * 2 = 8/3 = 2 2/3
5/12 : 4 i 3/8= 5/12 : 35/8 = 5/12 * 8/35 = 1/3 * 2/7 = 2/21
2 i 7/8 : 3/16=23/8 * 16/3 = 23*2/3 = 46/3 = 15 1/3
