6 - 3 2/7 =

1 3/4 - 1/5 =

8 2/9 - 4 1/4 =

7 1/5 - 3 4/7 =

Answer 1

1/3 + 1/4 = 4/12 + 3/12 = 7/12

 

5/8 + 2/7 = 35/56 + 16/56 = 51/56

 

 

14/15 + 1/12 = 56/60 + 5/60 = 61/60 = 1 1/60

 

8/9 + 4/11 = 88/99 + 36/99 = 124/99 = 1 25/99

 

 

16/17 + 1/2 = 32/34 + 17/34 = 49/34 = 1 15/34

 

6 - 3 2/7 = 5 7/7 - 3 2/7 = 2 5/7

 

1 3/4 - 1/5 = 1,75 - 0,2 = 1,55

 

8 2/9 - 4 1/4 = 8 8/36 - 4 9/36 = 7 44/36 - 4 9/36 = 3 35/36

 

7 1/5 - 3 4/7 = 7 7/35 - 3 20/35 = 6 42/35 - 3 20/35 = 3 22/35
