[ 1/1 Equation]
    Work: Find the solution of equation 1.5 = 450/（450-x） .
    Question type: Equation
    Solution:Original question:
     
3
2
 = 450 ÷ (450 − x )
     Multiply both sides of the equation by:(450 − x )
     
3
2
(450 − x ) = 450
    Remove a bracket on the left of the equation:：
     
3
2
 × 450 −
3
2
 x = 450
    The equation is reduced to :
     675 −
3
2
 x = 450

    Transposition :
      -
3
2
 x = 450 − 675

    Combine the items on the right of the equation:
      -
3
2
 x = - 225

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     225 =
3
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 :
     
3
2
 x = 225

    The coefficient of the unknown number is reduced to 1 :
      x = 225 ÷
3
2
        = 225 ×
2
3
        = 75 × 2

    We obtained :
      x = 150
    This is the solution of the equation.
