2 1/3-1 2/9=2 3/9 -1 2/9=1 1/9
2 1/3-(-1 2/9)=2 3/9+1 2/9=3 5/9
-2 1/3-1 2/9=-2 3/9-1 2/9=-3 5/9
-2 1/3-(-1 2/9)=-2 3/9+1 2/9=-1 1/9
Odpowiedź:
2 1/3 - 1 2/9 = 7/3 - 11/9 = 21/9 - 11/9 = 10/9 = 1 1/9
2 1/3 - (-1 2/9) = 7/3 + 11/9 = 21/9 + 11/9 = 32/9 = 3 5/9
- 2 1/3 - 1 2/9 = - 7/3 - 11/9 = - 21/9 - 11/9 = - 32/9 = - 3 5/9
- 2 1/3 - (-1 2/9) = - 7/3 + 11/9 = - 21/9 + 11/9 = - 10/9 = - 1 1/9
