    Work: Find the solution of equation (450+x)/(1500+x) = 51% .
    Question type: Equation
    Solution:Original question:

(

450

+

x

)

÷

(

1500

+

x

)

=

51 100

Multiply both sides of the equation by:

(

1500

+

x

)

(

450

+

x

)

=

51 100

(

1500

+

x

)

    Remove a bracket on the left of the equation:：

450

+

x

=

51 100

(

1500

+

x

)

    Remove a bracket on the right of the equation:：

450

+

x

=

51 100

×

1500

+

51 100

x

    The equation is reduced to :

450

+

x

=

765

+

51 100

x

    Transposition :

x

−

51 100

x

=

765

−

450

    Combine the items on the left of the equation:

49 100

x

=

765

−

450

    Combine the items on the right of the equation:

49 100

x

=

315

    The coefficient of the unknown number is reduced to 1 :

x

=

315

÷

49 100

=

315

×

100 49

=

45

×

100 7

    We obtained :

x

=

4500 7

    This is the solution of the equation.

    Convert the result to decimal form :

x

=

642.857143
