[ 1/1 Equation]
    Work: Find the solution of equation 1/{1+1/[32+(1/(1+(1/x)))]} = 98/101 .
    Question type: Equation
    Solution:Original question:
     1 ÷ (1 + 1 ÷ (32 + (1 ÷ (1 + (1 ÷ x ))))) = 98 ÷ 101
     Multiply both sides of the equation by:(1 + 1 ÷ (32 + (1 ÷ (1 + (1 ÷ x )))))
     1 = 98 ÷ 101 × (1 + 1 ÷ (32 + (1 ÷ (1 + (1 ÷ x )))))
    Remove a bracket on the right of the equation::
     1 = 98 ÷ 101 × 1 + 98 ÷ 101 × 1 ÷ (32 + (1 ÷ (1 + (1 ÷ x ))))
    The equation is reduced to :
     1 =

÷ (32 + (1 ÷ (1 + (1 ÷ x ))))
     Multiply both sides of the equation by:(32 + (1 ÷ (1 + (1 ÷ x ))))

    After the equation is converted into a general formula, there is a common factor:
    ( x - 2 )
    From
        x - 2 = 0

    it is concluded that::
        x1=2

    Solutions that cannot be obtained by factorization:
        x2≈-0.970588 , keep 6 decimal places
    
    There are 2 solution(s).
