[ 1/1 Equation]
    Work: Find the solution of equation (1/4-x/3)/(1/3-x/2) = (1/5-x/4)/(1/4-x/3) .
    Question type: Equation
    Solution:Original question:
     (1 ÷ 4 x ÷ 3) ÷ (1 ÷ 3 x ÷ 2) = (1 ÷ 5 x ÷ 4) ÷ (1 ÷ 4 x ÷ 3)
     Multiply both sides of the equation by:(1 ÷ 3 x ÷ 2) ,  (1 ÷ 4 x ÷ 3)
     (1 ÷ 4 x ÷ 3)(1 ÷ 4 x ÷ 3) = (1 ÷ 5 x ÷ 4)(1 ÷ 3 x ÷ 2)
    Remove a bracket on the left of the equation::
     1 ÷ 4 × (1 ÷ 4 x ÷ 3) x ÷ 3 × (1 ÷ 4 x ÷ 3) = (1 ÷ 5 x ÷ 4)(1 ÷ 3 x ÷ 2)
    Remove a bracket on the right of the equation::
     1 ÷ 4 × (1 ÷ 4 x ÷ 3) x ÷ 3 × (1 ÷ 4 x ÷ 3) = 1 ÷ 5 × (1 ÷ 3 x ÷ 2) x ÷ 4 × (1 ÷ 3 x ÷ 2)
