Answer 1

1/4 + 3/4 = 4/4 = 1

3/5 + 4/5 = 7/5 = 1 i 2/5

5/7 + 1 i 4/7 = 5/7 + 11/7 = 16/7 = 2 i 2/7

2 i 5/6 + 3 i 1/6 = 3 i 6/6 = 4

5/12 + 7/12 + 9/12 = 21/12 = 1 i 9/12 = 1 i 3/4

2 i 3/8 + 3 i 5/8 + 4 i 7/8 = 19/8 + 29/8 + 39/8 = 10 i 7/8

 

1/4 + 1/5 = 5/20 + 4/20 = 9/20

2/3 + 5/7 = 14/21 + 15/21 = 29/21 = 1 i 8/21

1 i 1/10 + 5 i 4/5 = 1 i 1/10 + 5 i 8/10 = 6 i 9/10

5/6 + 3 i 11/12 = 10/12 + 3 i 11/12 = 10/12 + 47/12 = 57/12 = 4 i 4/12 = 4 i 3/4

1/4 + 1/5 + 3/10 = 5/20 + 4/20 + 6/20 = 15/20 = 3/4

5 + 7 i 8/9 + 4 i 1/2 = 90/18 + 142/18 + 81/18 = 313/18 = 17 i 7/18

11/12 - 4/12 = 7/12

20 - 3/7 = 20/1 - 3/7 = 140/7 = 3/7 = 137/7 = 19 i 4/7

14 i 2/5 - 3/5 = 72/5 - 3/5 = 69/5 = 18 i 1/5

32 - 4 i 5/6 = 32/1 - 29/6 = 192/6 - 29/6 = 163/6 = 27 1/6

85 i 10/11 - 26 i 4/11 =  59 i 6/11

27 i 3/8 - 19 i 5/8 = 26 i 11/8 - 19 i 5/8 = 7 i 6/8 = 7 i 3/4
