    Work: Find the solution of equation （X*1.13-0.42*1.13)/(X*1.13) = 0 .
    Question type: Equation
    Solution:Original question:

(

X

×

113 100

−

21 50

×

113 100

)

÷

(

X

×

113 100

)

=

0

Multiply both sides of the equation by:

(

X

×

113 100

)

(

X

×

113 100

−

21 50

×

113 100

)

=

0

    Remove a bracket on the left of the equation:：

X

×

113 100

−

21 50

×

113 100

=

0

    The equation is reduced to :

X

×

113 100

−

2373 5000

=

0

    Transposition :

113 100

X

=

0

+

2373 5000

    Combine the items on the right of the equation:

113 100

X

=

2373 5000

    The coefficient of the unknown number is reduced to 1 :

X

=

2373 5000

÷

113 100

=

2373 5000

×

100 113

=

2373 50

×

1 113

    We obtained :

X

=

2373 5650

    This is the solution of the equation.

    Convert the result to decimal form :

X

=

0.42
