[ 1/1 Equation]
    Work: Find the solution of equation （2x-1）/（x-1） = 0 .
    Question type: Equation
    Solution:Original question:

(

2

x

−

1

)

÷

(

x

−

1

)

=

0

Multiply both sides of the equation by:

(

x

−

1

)

(

2

x

−

1

)

=

0

    Remove a bracket on the left of the equation:：

2

x

−

1

=

0

    Transposition :

2

x

=

0

+

1

    Combine the items on the right of the equation:

2

x

=

1

    The coefficient of the unknown number is reduced to 1 :

x

=

1

÷

2

=

1

×

1 2

    We obtained :

x

=

1 2

    This is the solution of the equation.

    Convert the result to decimal form :

x

=

0.5
