1) 2/3 + 1/7 = 14+3/21 = 17/21

2) 1/3 + 1/12 = 4+1/12 = 5/12

3) 1/9 + 1/10 = 10+9/90 = 19/90

4) 1/4 + 1/9 = 9+4/36 = 13/36

5) 1/3 + 1/10 = 10+3/30 = 13/30

6) 1/3 + 1/9 = 3+1/9 = 4/9

7) 1/4 + 1/5 = 5+4/20 = 9/20

8) 5/6 + 1/10 = 25+3/30 = 28/30

9) 1/8 + 1/9 = 9+8/72 = 17/72

10) 2/7 + 3/10 = 20+21/70 = 41/70

11) 1/7 + 1/10 = 10+7/70 = 17/70

12) 1/6 + 1/12 = 2+1/12 = 3/12

13) 1/7 + 1/9 = 9+7/63 = 16/63

14) 5/6 + 1/8 = 40+6/24 = 46/24

15) 1/6 + 1/10 = 5+3/30 = 8/30

16) 1/7 + 1/8 = 8+7/56 = 15/56

17) 1/8 + 1/10 = 10+8/80 = 18/80

18) 1/6 + 1/9 = 9+6/54 = 15/54

19) 5/7 + 2/9 = 45+14/63 = 59/63

20) 1/7 + 7/10 = 10+49/70 = 59/70

Acho q é isso
