回答1:

1÷ (2÷3) ÷(3÷4)÷(4÷5)÷(5÷6)
=1×(3÷2)×(4÷3)×(5÷4)×(6÷5)
=1×3÷2×4÷3×5÷4×6÷5
=1×3×4×5×6÷2÷3÷4÷5
=3×(4×5)×6÷2÷3÷4÷5
=3×20×6÷2÷3÷4÷5
=60×6÷2÷3÷4÷5
=360÷2÷3÷4÷5
=360÷(2×3)÷4÷5
=360÷6÷4÷5
=60÷4÷5
=60÷ (4×5)
=60÷20
=3
用小学四年级方法,尽量用上运算定律,尽量能口算

回答2:

1除以后面那些相乘就可以了,后面那些相乘得1/3
所以结果是3

回答3:

1x3/2x4/3x5/4x6/5
=6/2
=3

回答4:

1*(3/2)*(4/3)*(5/4)*(6/5)=3

回答5:

先算括号再挨着算
