[ 1/1 Equation]
    Work: Find the solution of equation 15 = 100×(X-60)/(X×30/100) .
    Question type: Equation
    Solution:Original question:
     15 = 100( X 60) ÷ ( X × 30 ÷ 100)
     Multiply both sides of the equation by:( X × 30 ÷ 100)
     15( X × 30 ÷ 100) = 100( X 60)
    Remove a bracket on the left of the equation::
     15 X × 30 ÷ 100 = 100( X 60)
    Remove a bracket on the right of the equation::
     15 X × 30 ÷ 100 = 100 X 100 × 60
    The equation is reduced to :
     
9
2
X = 100 X 6000

    Transposition :
     
9
2
X 100 X = - 6000

    Combine the items on the left of the equation:
      -
191
2
X = - 6000

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     6000 =
191
2
X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
191
2
X = 6000

    The coefficient of the unknown number is reduced to 1 :
      X = 6000 ÷
191
2
        = 6000 ×
2
191

    We obtained :
      X =
12000
191
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 62.827225
