Szczegółowe wyjaśnienie:
4p(1/2p -1/3) -3p(1/6p+1/9)=
=2p²-4/3p- 1/2p² -1/3p=1 1/2p²-5/3p=1 1/2p²-1 2/3p
-5(1/4x+1/2y)+3(3/4x-1/2y)=
=-5/4x-5/2y+9/4x-3/2y=x-4y
(1/2m-1/5):2 +(1/2m+2/5):4=
=1/4m -1/10+2m+1/10=2 1/4m
(2/3a+3/4b):6 - (1/3a+1/2b):4=
=1/9a+1/8b-1/12a -1/8b=4/36a -3/36a=1/36a
6(1/9u+1/12) -(1/2u+3/4):3=
=2/3u+1/2-1/6u-1/4=
=4/6u-1/6u+2/4-1/4=1/2u-1/4
