Daje naj
P.s. Liczcie działaniami a nie same wyniki . Bo same wyniki mam na końcu książki :)

Answer 1

A) -1 1/4*(-4)= - 5/4 *(-4)= 5
b)-6 2/3 ;2= - 20/3 :2= -20/3 *1/2= 10/3=3 1/3
c)-0,2* (-0,2)= 0,04
d)-3 1/3 * (-3)= 10/3 *3 = 10
e)(-3)@2 * 1/3= 9*1/3 =9/3=3
f) (1/3)@2 * (-9)= 1/9*(-9)= -1
g) [email protected] : 1/2=-36 : 1/2=-72
h)3 3/4 : (-1,25)@2= 15/4 :(-5/4)@2= 15/4: 25/16=15/4*16/25=12/5= 2,4

Answer 2

A) -1 1/4 x (-4) =-5/4*(-4/1)=5/1=5
b) -6 2/3 : 2 =-20/3:2/1=-20/3*1/2=-10/3=-3 1/3             
c) -0,2 x (-0,2) = 0,04                    
d) -3 1/3 x (-3) = -4/3*(-3/1)=4/1=4 
e) (-3)@2 x 1/3 =9*1/3=9/1*3/1=27/3=9
f) (1/3)@2 x (-9) = 1/9*(-9/1)=-1
g) [email protected] : 1/2 =-36*2/1=72/1=72   
h) 3 3/4 : (-1,25)@2 =3 3/4:(-1 1/4)@2=3 3/4:(-5/4)@2=3 3/4:(-25/16)=15/4*(-16/25)=
=3/1*(-4/5)=-12/5=-2 2/5
