    Work: Find the solution of equation (X-100)÷200 = (X-20)÷400 .
    Question type: Equation
    Solution:Original question:
     ( X 100) ÷ 200 = ( X 20) ÷ 400
    Remove the bracket on the left of the equation:
     Left side of the equation = X ×
1
200
100 ×

= ( X 20) ÷ 400
    Remove the bracket on the right of the equation:
     Right side of the equation = X ×

    Combine the items on the right of the equation:
     
1
400
X =
9
20

    The coefficient of the unknown number is reduced to 1 :
      X =
9
20
÷

400
        =
9
20
× 400
        = 9 × 20

    We obtained :
      X = 180
    This is the solution of the equation.
