[ 1/1 Equation]
    Work: Find the solution of equation 1/2(2/5(5/9(9/8(1-x)-1-x)-1-x)-1-x)-1-x = 1/3(3/4(4/6(6/10(1-x)-x)-x)-x)-x .
    Question type: Equation
    Solution:Original question:
     1 ÷ 2 × (2 ÷ 5 × (5 ÷ 9 × (9 ÷ 8 × (1 − x ) − 1 − x ) − 1 − x ) − 1 − x ) − 1 − x = 1 ÷ 3 × (3 ÷ 4 × (4 ÷ 6 × (6 ÷ 10 × (1 − x ) − x ) − x ) − x ) − x
     Left side of the equation =
1
2
(2 ÷ 5 × (5 ÷ 9 × (9 ÷ 8 × (1 − x ) − 1 − x ) − 1 − x ) − 1 − x ) − 1 − x
    The equation is transformed into :
