Tarefa

Calcule, simplificando ao máximo o resultado:

1/4 + 3/7  = 19/28

2/3 - 7/8  = -5/24

4/7 - 7/8  = -17/56

6/5 - 5/9  = 29/45

3/9 - 3/4  = -5/12  

1/11 + 2/9  = 31/99

8/13 - 5/2  = -49/26

9/4 + 9/11  = 135/44

7/2 - 4/10  =  31/10

6/7- 8/3  = -38/21

13/14 + 16/2  = 125/14

12/15 + 17/20  = 33/20

11/13 - 13/11  = -48/143

19/15 + 10/23  = 587/345

27/20 - 19/26  = 161/260

29/31 + 25/33  = 1732/1023

37/29 - 27/36  = 61/116

33/41 + 36/30  = 411/205
