3/8 x (-0,9) x (-16/3) x 10 =
3/8*-(16/3) *-(0,9) *10 = 2* -9= 18 (minus i minus daje plus a ułamki się skraca )
5 x (0,25) x 0,2 x (-4) =
5* 1/4*1/5*(-4)= 1*(-1) =-1(ułamki pomnożone z liczbami całymi)
(-2,5) x 0,2 x (-10) x 2=
-5/2* 1/5*-10*2=-1/2*-20= -10
(-6) x (-4/7) x 2/5 x (-7) x 5/12 =
84*40/12
