Answer 1

4/19 * 2 i 3/8 = 4/19 * 19/8 = 76/152 = 1/2

3 i 3/8 * 8/9 = 27/8 * 8/9 = 216/72 = 3

7/11 * 12/24 = 7/11 * 1/2 = 7/22

1 i 1/2 * 2/3 = 3/2 * 2/3 = 6/6 = 1 

3 i 1/5 * 2 i 1/4 = 16/5 * 9/4 = 144/20 = 7 i 4/20 = 7 i 1/5

1/9 * 9 i 1/2 = 1/9 * 19/2 = 19/18 = 1 i 1/18

3/7 : 7/3 = 3/7 * 3/7 = 9/49 

4 i 1/5 : 7/10 = 21/5 * 10/7 = 210/35 = 6

1/2 : 1 i 1/4 = 1/2 : 5/4 = 1/2 * 4/5 = 4/10 = 2/5 

1 i 1/8 : 8 = 9/8 * 1/8 = 9/64 

4/8 : 1/2 = 4/8 * 2/1 = 8/8 = 1

3 i 3/11 : 3 = 36/11 * 1/3 = 36/33 = 1 i 3/33 = 1 i 1/11

2 i 3/7 : 4 i 6/7 = 17/7 : 34/7 = 17/7 * 7/34 = 119/238 = 1/2
