Oblicz -1 1/3-2/9+1/6 1 1/8-2 1/4-(-1/2) (-2.1)+1/5-3
-1 1/3-2/9+1/6 = - 4/3 - 2/9 + 1/6 = - 24/18 - 4/18 + 3/18 = - 25/18
1 1/8-2 1/4-(-1/2) = 9/8 - 9/4 + 1/2 = 9/8 - 18/8 + 4/8 = - 5/18
(-2,1)+1/5-3 = - 2 1/10 + 1/5 - 3 = - 21/10 + 1/5 - 3 = - 21/10 + 2/10 - 3 = -19/10 - 3 = -19/10 - 30/10 = 11/10 = 1 1/10 = 1,1
pozdrawiam :)
