[ 1/1 Equation]
    Work: Find the solution of equation （12.5*X*1.67*.4）/（1-12.5*X*1.67*.4） = 30% .
    Question type: Equation
    Solution:Original question:
     (

) ÷ (1 −
25
2
 X ×
167
100
 ×

) =
30
100
     Multiply both sides of the equation by:(1 −

    The equation is reduced to :
     
167
20
 X =
3
10
 −
501
200
 X

    Transposition :
     
167
20
 X +
501
200
 X =
3
10

    Combine the items on the left of the equation:
     
2171
200
 X =
3
10

    The coefficient of the unknown number is reduced to 1 :
      X =
3
10
 ÷
2171
200
        =
3

200
2171
        = 3 ×
20
2171

    We obtained :
      X =
60
2171
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 0.027637
