[ 1/1 Equation]
    Work: Find the solution of equation 0.15×a+a = 270000 .
    Question type: Equation
    Solution:Original question:
     
3
20
a + a = 270000
     Left side of the equation =
23
20
a
    The equation is transformed into :
     
23
20
a = 270000

    The coefficient of the unknown number is reduced to 1 :
      a = 270000 ÷
23
20
        = 270000 ×
20
23

    We obtained :
      a =
5400000
23
    This is the solution of the equation.

    Convert the result to decimal form :
      a = 234782.608696
