脱式计算，能简算简算
5/6-2/3+1/8
7/10+3/8-1/5
5/16+(1/9+8/9)
5/6-2/3+1/8
=20/24-16/24+3/24
=4/24+3/24
=7/24
7/10+3/8-1/5
=28/40+15/40-8/40
=43/40-8/40
=35/40
=7/8
5/16+(1/9+8/9)
=5/16+1
=1又5/6
再问： 6/11+7/8-6/11 9/23+(14/23-9/20) 9-8/17-9/17 13/32-(3/4-3/8) 3/13+6/7+10/13 2-8/13-5/13
再答： 6/11+7/8-6/11 =6/11-6/11+7/8 =0+7/8 =7/8 9/23+(14/23-9/20) =9/23+14/23-9/20 =1-9/20 =11/20 9-8/17-9/17 =9-(8/17+9/17) =9-1 =8 13/32-(3/4-3/8) =13/32-3/8 =13/32-12/32 =1/32 3/13+6/7+10/13 =3/13+10/13+6/7 =1+6/7 =1又6/7 2-8/13-5/13 =2-(8/13+5/13) =2-1 =1
