(1/2+1/3)×6-2×0,1=
(12 1/5-4 2/3)÷(1 3/4×8)=

Answer 1

6 1/3-1/3×1 4/5+2=19/3-1/3*9/5+2=19/3-3/5+2=95/15-9/15+30/15=86/15+30/15=
=116/15=7 11/15
3 3/4×4/9-4/9+4=15/4*4/9-4/9+4=5/3-4/9+4=15/9-4/9+36/9=11/9+36/9=47/9=5 2/9

(1/2+1/3)×6-2×0,1=(3/6+2/6)*6*1/10=5/6*6*1/10=5*1/10=5/10=1/2

(12 1/5-4 2/3)÷(1 3/4×8)= 61/5-14/3):(7/4*8)=(183/15-70/15):14=113/15*1/14=113/210
