[ 1/1 Equation]
    Work: Find the solution of equation 80×(100%+x%) = 90 .
    Question type: Equation
    Solution:Original question:
     80(
100
100
+ x ) = 90
    Remove the bracket on the left of the equation:
     Left side of the equation = 80 ×
100
100
+ 80 x
                                             = 80 + 80 x
    The equation is transformed into :
     80 + 80 x = 90

    Transposition :
     80 x = 9080

    Combine the items on the right of the equation:
     80 x = 10

    The coefficient of the unknown number is reduced to 1 :
      x = 10 ÷ 80
        = 10 ×
1
80
        = 1 ×
1
8

    We obtained :
      x =
1
8
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.125
