(если что я не переписывала пример)

1) (3+1) + (1/2 + 5/6) =4 4/3 = 4 + 1 1/3 = 5 1/3

2) (4+9) + (2/5 + 3/7) =13 29/35

3) (8+2) + (3/4 + 7/8) = 10 13/8 =10 + 1 5/8 = 11 5/8

4) (2+1) + (3/8 + 5/6) =3 29/24 = 3 + 1 5/24

5) (6+1) + (1/5 + 2/3) =7 13/15

6) (4+8) + (3/8+1/2) =12 7/8

1) 6 3/3 - 5 2/3 =1 1/3

2) 5 3/3 - 5 2/3 =1/3

3) 11 8/8 - 9 3/8 =2 5/8

4)10 3/3 - 6 2/3 =4 1/3

5) 7 7/7 - 3 2/7 = 4 5/7

6)5 6/13 - 1 13/13 = 4 19/13 - 1 13/13 =3 6/13
