[ 1/1 Equation]
    Work: Find the solution of equation （1.11+X）/(3.85+X) = 0.3 .
    Question type: Equation
    Solution:Original question:
     (
111
100
 + X ) ÷ (
77
20
 + X ) =
3
10
     Multiply both sides of the equation by:(
77
20
 + X )
     (
111
100
 + X ) =
3
10
(
77
20
 + X )
    Remove a bracket on the left of the equation:：
     
111
100
 + X =
3
10
(
77
20
 + X )
    Remove a bracket on the right of the equation:：
     
111
100
 + X =
3
10
 ×
77
20
 +
3
10
 X
    The equation is reduced to :
     
111
100
 + X =
231
200
 +
3
10
 X

    Transposition :
      X −
3
10
 X =
231
200
 −
111
100

    Combine the items on the left of the equation:
     
7
10
 X =
231
200
 −
111
100

    Combine the items on the right of the equation:
     
7
10
 X =
9
200

    The coefficient of the unknown number is reduced to 1 :
      X =
9
200
 ÷
7
10
        =
9
200
 ×
10
7
        =
9
20
 ×
1
7

    We obtained :
      X =
9
140
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 0.064286
