[ 1/1 Equation]
    Work: Find the solution of equation 0.3/(2000-p/2000) = -2 .
    Question type: Equation
    Solution:Original question:
     
3
10
 ÷ (2000 − p ÷ 2000) = - 2
     Multiply both sides of the equation by:(2000 − p ÷ 2000)
     
3
10
 = - 2(2000 − p ÷ 2000)
    Remove a bracket on the right of the equation:：
     
3
10
 = - 2 × 2000 + 2 p ÷ 2000
    The equation is reduced to :
     
3
10
 = - 4000 +

1000
 p

    Transposition :
      -

    Combine the items on the right of the equation:
      -
1
1000
 p = -
40003
10

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
40003
10
 =
1
1000
 p

    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 :
     
1
1000
 p =
40003
10

    The coefficient of the unknown number is reduced to 1 :
      p =
40003
10
 ÷

1000
        =
40003
10
 × 1000
        = 40003 × 100

    We obtained :
      p = 4000300
    This is the solution of the equation.
