Answer 1

-1 1/2 : -0,06=-3/2 * -100/6=-1/1 * -50/2= 25

-2 2/3 : 1.2=-5/3* 10/12= -50/36

2/3 : -6=2/3* -1/6=1/3* -1/3=-1/9

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

-2,75 : -2,2=-275/100 *-10/22=-275/10 *-1/22=275/220

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

Answer 2

(-1  1/2 ):(-0,06)= -1,56

(-2  2/3):1,2= -1 17/18

 2/3:(-6)= -1/9

(-0,45): 1  4/5 = -1/2

(-2,75):(-2,2)= 1 1/4

(-3,5):(-1  2/5)= 4 1/2
