Szczegółowe wyjaśnienie:
-1 1/4 * (-4)=-5/4*(-4)=5
-6 2/3 : 2=-20/3:2= -20/3*1/2= -20/6= -3 2/6=-3 1/3
-0,2 * (-0,2)=0,04
-3 1/3 * (-3)=-10/3*(-3)=10
(-3)² * 1/3=9*1/3=3
(1/3)² * (-9)=1/9*(-9)= -1
-6² : 1/2 = -36 :1/2= -36*2= -72
3 3/4 : (-1,25)²=15/4: (-1 1/4)^2=15/4: (-5/4)^2= 15/4 :25/16=15/4*16/25=12/5=2 2/5
