[ 1/1 Equation]
    Work: Find the solution of equation x/(1+200/100)-x/(1+230/100) = 300 .
    Question type: Equation
    Solution:Original question:
      x ÷ (1 + 200 ÷ 100) − x ÷ (1 + 230 ÷ 100) = 300
     Multiply both sides of the equation by:(1 + 200 ÷ 100)
      x − x ÷ (1 + 230 ÷ 100) × (1 + 200 ÷ 100) = 300(1 + 200 ÷ 100)
    Remove a bracket on the left of the equation:：
      x − x ÷ (1 + 230 ÷ 100) × 1 − x ÷ (1 + 230 ÷ 100) × 200 ÷ 100 = 300(1 + 200 ÷ 100)
    Remove a bracket on the right of the equation:：
      x − x ÷ (1 + 230 ÷ 100) × 1 − x ÷ (1 + 230 ÷ 100) × 200 ÷ 100 = 300 × 1 + 300 × 200 ÷ 100
    The equation is reduced to :
      x − x ÷ (1 + 230 ÷ 100) × 1 − x ÷ (1 + 230 ÷ 100) × 2 = 300 + 600
    The equation is reduced to :
      x − x ÷ (1 + 230 ÷ 100) × 1 − x ÷ (1 + 230 ÷ 100) × 2 = 900
     Multiply both sides of the equation by:(1 + 230 ÷ 100)
      x (1 + 230 ÷ 100) − x × 1 − x ÷ (1 + 230 ÷ 100) × 2(1 + 230 ÷ 100) = 900(1 + 230 ÷ 100)
    Remove a bracket on the left of the equation:
      x × 1 + x × 230 ÷ 100 − x × 1 − x ÷ (1 + 230 ÷ 100) × 2(1 + 230 ÷ 100) = 900(1 + 230 ÷ 100)
    Remove a bracket on the right of the equation:：
      x × 1 + x × 230 ÷ 100 − x × 1 − x ÷ (1 + 230 ÷ 100) × 2(1 + 230 ÷ 100) = 900 × 1 + 900 × 230 ÷ 100
    The equation is reduced to :
      x × 1 + x ×

 − x × 1 − x ÷ (1 + 230 ÷ 100) × 2(1 + 230 ÷ 100) = 900 + 2070
    The equation is reduced to :

10
 x − x ÷ (1 + 230 ÷ 100) × 2(1 + 230 ÷ 100) = 2970
     Multiply both sides of the equation by:(1 + 230 ÷ 100)

10
 x (1 + 230 ÷ 100) − x × 2(1 + 230 ÷ 100) = 2970(1 + 230 ÷ 100)

 x = 9801

    The coefficient of the unknown number is reduced to 1 :
      x = 9801 ÷
99

99
        = 99 × 100

    We obtained :
      x = 9900
    This is the solution of the equation.
