[ 1/1 Equation]
    Work: Find the solution of equation 90 = 100/(1+x) .
    Question type: Equation
    Solution:Original question:
     90 = 100 ÷ (1 + x )
     Multiply both sides of the equation by:(1 + x )
     90(1 + x ) = 100
    Remove a bracket on the left of the equation::
     90 × 1 + 90 x = 100
    The equation is reduced to :
     90 + 90 x = 100

    Transposition :
     90 x = 10090

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

    The coefficient of the unknown number is reduced to 1 :
      x = 10 ÷ 90
        = 10 ×
1
90
        = 1 ×
1
9

    We obtained :
      x =
1
9
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 0.111111
