[ 1/1 Equation]
    Work: Find the solution of equation x/(x+1000) = 0.80 .
    Question type: Equation
    Solution:Original question:
      x ÷ ( x + 1000) =
4
5
     Multiply both sides of the equation by:( x + 1000)
      x =
4
5
( x + 1000)
    Remove a bracket on the right of the equation::
      x =
4
5
x +
4
5
× 1000
    The equation is reduced to :
      x =
4
5
x + 800

    Transposition :
      x
4
5
x = 800

    Combine the items on the left of the equation:
     
1
5
x = 800

    The coefficient of the unknown number is reduced to 1 :
      x = 800 ÷
1
5
        = 800 × 5

    We obtained :
      x = 4000
    This is the solution of the equation.
