    Work: Find the solution of equation (2.7*x)/(2.7+x) = 1 .
    Question type: Equation
    Solution:Original question:

(

27 10

x

)

÷

(

27 10

+

x

)

=

1

Multiply both sides of the equation by:

(

27 10

+

x

)

(

27 10

x

)

=

1

(

27 10

+

x

)

    Remove a bracket on the left of the equation:：

27 10

x

=

1

(

27 10

+

x

)

    Remove a bracket on the right of the equation:：

27 10

x

=

1

×

27 10

+

1

    Transposition :

27 10

x

−

1

x

=

27 10

    Combine the items on the left of the equation:

17 10

x

=

27 10

    The coefficient of the unknown number is reduced to 1 :

x

=

27 10

÷

17 10

=

27 10

×

10 17

=

27

×

1 17

    We obtained :

x

=

27 17

    This is the solution of the equation.

    Convert the result to decimal form :

x

=

1.588235
