Question

-1,1(3):[-1 la 1 pe 6+1,16:(-1 la 2 pe 6+3,2(6)]

Answer 1

-1,1(3):[-1  1/6+1,16:(-1  2/6+3,2(6)]=
=-(113-11)/90:[-7/6+1,16:(-8/6+(326-32)/90)]=
=-102/90:[-7/6+116/100:(-8/6+294/90)]=
=-17/15:[-7/6+58/50:(-8/6+49/15)]=
=-17/15:[-7/6+58/50:(-40+98)/30)]=
=-17/15:(-7/6+58/50:58/30)=
=-17/15:(-7/6+58/50×30/58)=
=-17/15:(-7/6+3/5)=
=-17/15:(-35+18)/30=
=-17/15:(-17/30)=
=17/15×30/17=2
