回答1:

11/8-(5/6+3/8)
= 11/8-5/6-3/8
=( 11/8-3/8)-5/6
=1-5/6
=1/6
你后面两道题是不是这样打错了吧

5/9+4/11+6/11+4/9
5-3/7-4/7

回答2:

11/8-(5/6+3/8)=11/8 -5/6 -3/8=11/8-3/8-5/6=1-5/6=1/6
9/5+11/4+11/6+9/4=11/4+9/4+9/5+11/6=5+9/4+11/6=109/12
5-7/3-7/4=8/3-7/4=11/12

回答3:

11/8-(5/6+3/8)
=11/8-5/6-3/8

=1-5/6
=1/6
9/5+11/4+11/6+9/4
=5+81/20

=181/20
5-7/3-7/4
=11/12

回答4:

9分之5+11分之3+3又9分之4+11分之8
=5/9+3/11+3+4/9+8/11
=3+1+1
=5
13又5分之1÷1又5分之1×1又11分之4
=66/5÷6/5×15/11
=11×15/11
=15
