Answer 1

1/3 + 1/3 = 2/3
1/4 + 1/4 = 2/4 =  1/2
3/4 + 1/4 = 4/4 = 1
2/4 + 3/4 = 5/4 = 1 1/4
1/5 + 2/5 = 3/5
3/5 + 2/5 = 5/5 = 1
3/6 + 1/6 = 4/6
2/6 + 3/6 = 5/6
4/6 + 2/7 = 28/42 + 12/42 = 40/42 = 20/21
5/7 + 1/7 = 6/7

Answer 2

1/3 +1/3 = 2/3
1/4 + 1/4 = 2/4 atau 1/2
3/4 + 1/4 = 4/4 atau 1
2/4 + 3/4 = 5/4 atau 1 1/4
1/5 + 2/5 = 3/5
3/5 + 2/5 = 5/5 atau 1
3/6 + 1/6 = 4/6 atau 2/3
2/6 + 3/6 = 5/6
4/6 + 2/7 = 28/42 + 12/42 = 40/42 = 20/21
5/7 + 1/7 = 6/7
