回答1：

5/6*1/7+1/6 /7
=5/6*1/7+1/6*1/7
=(5/6+1/6)*1/7
=1*1/7
=1/7

8-(5/8 / 5/24+2/11)
=8-[(5/5)/(8/24)+2/11]
=8-(1/(1/3)+2/11)
=8-3-2/11
=5-2/11
=55/11-2/11
=53/11

7/11除[2/5-(1-7/10)]
7/11 / [2/5-1+7/10]
=7/11 / [4/10-10/10+7/10]
=7/11/ [(4-10+7)/10]
=7/11/(1/10)
=7*10/11
=70/11

25/12-4/9-5/9-1/12
=(25/12-1/12)-(4/9+5/9)
=24/12-9/9
=2-1
=1

回答2：

5/6X1/7+1/6除7
=5/6x1/7+1/6x1/7
=(5/6+1/6)x1/7
=1x1/7
=1/7

8-（5/8除5/24+2/11)
=8-3+2/11
=5+2/11
=5又2/11

7/11除[2/5-(1-7/10)]
=0.7÷（0.4-1+0.7）
=0.7÷0.1
=7

25/12-4/9-5/9-1/12

=（25/12-1/12）-（4/9+5/9）
=2-1
=1
