Oblicz : -1 1/3 - 2/9 + 1/6 1 1/8 - 2 1/4 - ( - 1/2) (-2,1)+ 1/3 - 3 PS. ukośniki to kreski ulamkowe =)

-1 1/3 - 2/9+ 1/6= -1 6/18 - 4/18 + 3/18= -1 7/18 1 1/8 - 2 1/4 - (-1/2)= 1 1/8 - 2 2/8 + 4/8 = 1 5/8 - 2 2/8= 13/8 - 18/8 = - 5/8 (-2,1) + 1/3 -3 = -2 1/10 +1/3 -3 = -2 3/30 + 10/30 - 3 = -5 3/30 + 10/30 = -4 27/30

a) -1 1/3 - 2/9 + 1/6= -4/3 - 2/9 + 1/6 = -12/9 - 2/9 + 1/6= -24/18 - 4/18 + 3/18= -25/18= - 1 i 7/18 b)1 1/8 - 2 1/4 - ( - 1/2)= 9/8 - 9/4 + 1/2= 9/8 - 18/8 + 4/8= -5/8 c)(-2,1)+ 1/3 - 3= -21/10 + 1/3 -3= -63/30 + 10/30 - 3= -53/30- 3= -1 i 23/30 - 3= -4 i 23/30
