pomóżcie z tym działaniem - 5,75 + 4 2/3 - 2 1/4 - ( -3 1/3 ) =
* 4 2/3 i 2 1/4 i - 3 1/3 = ułamki zwykłe
5,75 + 4 2/3 - 2 1/4 - ( -3 1/3 ) = 5 3/4 + 4 2/3 - 2 1/4- (-3 1/3)= 5 9/12 + 4 8/12 - 2 1/4 - (-3 1/3)=9 17/12 - 2 3/12 - 3 4/12= 9 14/12 - (- 3 4/12)=7 10/12
a tego drugiego niewiem o co hodzi
5 3/4+4 2/3-4 2/3+3 1/3=
23/4+14/3-14/3+10/3=
69/12+40/12=109/12
