Answer 1

Zad.1

(-2 i 2/3):1,2= (- 8/3) : 12/10 = (-8/3) * 10/12 = - 80/36 = -20/9 = - 2 i 2/9

 

2/3 : (-6)= = 2/3 * (-1/6) = - 2/18 = -1/9

 

(-0,45) : 1 i 4/5= (-45/100) : 9/5 = (-9/20) * 5/9 =  -5/20 = -1/4

 

(-2,75) : (-2,2)= (-275/100) : (-22/10) = (-11/4) * (-5/11) = 5/4 = 1 i ¼

 

(-3,5) : (-1i 2/5)= (-35/10) : (-7/5) = (-7/2) * (-5/7) = 5/2 = 2 i 1/2
