b) -3,5 x (-2/5) = -3 i 1/2 x (-2/5) = 1 i 2/5
c) 1,1 : (-0,125) = 1 i 1/10 : (-125/1000) = 1 i 1/10 x (-8) = -8 i 8/10
d) -0,24 : 4/5 = -24/100 x 5/4 = -120/400 =-3/10
e) 100 x (-157 3/4) = -15775
f) -6 : (-1,2) = -6 : (-6/5) = -6 x (-5/6) = 5
g) -49 3/8 : 0,001 = -49 i 3/8 x 1000 = -49375
mam nadzieję, że pomogłam ;)
