1) 350:(14+11)+5x[(-2)+(-3)]=350:25+5x-5=14+(-25)=14-25=-11
2) [1-(-0,4)x(-1⅔)]=(1-(- 4/10 )x(- 5/3 ))= (1- 4/6] = 2/6
3) (-2):(-5)-(-0,4):(-0,12)= (-2) x (-1/5) - (-4/10) x (-100/12)= 2/5 - 10/3 = 6/15 - 50/15 = -44/15

5) 4/5-(1,2 x 5/12-0,8):(-1/8)=4/5 - (12/10 x 5/12-0,8):(-1/8)=4/5 - (5/10 - 8/10) x 8= 8/10+3/10x8=8/10+24/10=32/10

1) 350:(14+11) + 5 x [(-2) + (-3) ] = 350 : 25 + 5 x 5 = 14+25 = 39
2) [1-(-0,4)x(1⅔)] = [1+0,4 x 5/3 ] = 14/10 x 5/3 = 14/6 = 2 i 2/6

Myślę że jest dobrze, pzdr.
