Plsss t na jutro!

Daje naj,

Answer 1

9/10 : (-3/4) = 9/10 x (-4/3) = 12/10 = 1 i 1/5

(-1i1/2):(0,06)= -1 i 1/2 x 100/600 = -3/2 x 100/600 = -50/200 = -1/4

(-2i2/3):1,2= - 8/3 : 12/10 = -8/3 x 10/12 = - 20/9 = -2 i 2/9

(2/3:(-6)= 2/3 : (-6/1) = 2/3 x (-1/6) = -1/9

(-0,45):1i4/5= -45/100 : 9/5 = - 9/100 x 1/9 = - 9/900 = - 1/100

(-0,75):(-2,2) = -3/4 : (-22/10) = -3/4 x -10/22 = 15/44

(-3,5):(-1i2/5)= -35/10 : (- 7/5) = - 35/10 x (-5/7) = 5/2 = 2 i 1/2
