28-2 4/21+1 3/7=28-2 4/21+ 1 9/21=28-3 13/21=24 8/21

6-(1 5/6 + 2 3/5)=6-(25/30+2 18/30)=6-2 43/30=6-3 13/30=2 17/30

28-2 i 4/21+1 i 3/7=27 i 13/21
6-(1 i 5/6 + 2 i 3/5)= 3 i 43/30
...5i 4/6+2 i 54/144= 7 i 150/144= 8 i 6/144=8 i 1/24
tego nie wiem 4 i 8/11 - 3 i 3/8 + 2 i 9/33 =
... 10 i 1/4
... -65/150
