Answer 1

-6-4 1/2=-6-9/2=-12/2-9/2=--21/2=-10 1/2

18+(-6 1/2)=18-13/2=36/2-13/2=23/2=11 1/2

-1 1/2-2/9+1/6=-3/2-2/9+1/6=-27/18-4/18+3/18=-31/18+3/18=-28/18=-1 10/18=-1 5/9

(-2,1)+1/9-3=-21/10+1/9-3/1=-189/90+10/9-270/90=-449/90=-4 89/90

36/10*4/9=144/90=1 54/90=1 6/10=1 3/5

-2+(-2 1/3):12/10=-2/1-7/3:12/10=-2/1-7/3*10/12=-2/1-70/36=-72/36-70/36=-142/36=-3 34/36=-3 17/18

(-12/5)*(-15/4)=180/20=9
