    Work: Find the solution of equation 12/103+20/200+X/1000+（65.5-X）/1650 = .3 .
    Question type: Equation
    Solution:Original question:
     12 ÷ 103 + 20 ÷ 200 + X ÷ 1000 + (
131

 −
87083
339900

    Combine the items on the right of the equation:
     
13
33000
 X =
14887
339900

    The coefficient of the unknown number is reduced to 1 :
      X =
14887
339900
 ÷
13
33000
        =
14887
339900

13

    We obtained :
      X =
1637570
14729
    This is the solution of the equation.

    By reducing fraction, we can get:
      X =
148870
1339

    Convert the result to decimal form :
      X = 111.179985
