5/6+1/12-2/3=10/9-(8/9+1/6)=(全要递等式,能简算的要简算)5/6+1/12-2/3=10/9-(8/9+1/6)=(全要递等式,能简算的要简算)5/6+1/12-2/3=1

5/6+1/12-2/3= 10/9-(8/9+1/6)= (全要递等式,能简算的要简算)
5/6+1/12-2/3= 10/9-(8/9+1/6)= (全要递等式,能简算的要简算)

5/6+1/12-2/3= 10/9-(8/9+1/6)= (全要递等式,能简算的要简算)
5/6+1/12-2/3
=10/12+1/12-8/12
=3/12
=1/4
10/9-(8/9+1/6)
=10/9-8/9-1/6
=2/9-1/6
=4/18-3/18
=1/18

5/6+1/12-2/3=5/6-2/3+1/12=1/6+1/12=3/12=1/4
10/9-(8/9+1/6)=10/9-8/9-1/6=2/9-3/18=1/18
