[ 1/1Inequality]
    Assignment:Find the solution set of inequality ((-10117010*x)+204269700*(1-x))/(sqrt(204269700*x^2+518921850000*(1-x)^2)) ≤0((-10117010*x)+204269700*(1-x))/(sqrt(204269700*x^2+518921850000*(1-x)^2)) = 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( -10117010 * x ) + 204269700 * ( 1 - x ) ) / ( sqrt ( 204269700 * x ^ 2 + 518921850000 * ( 1 - x ) ^ 2 ) ) ≤0 * ( ( -10117010 * x ) + 204269700 * ( 1 - x ) ) / ( sqrt ( 204269700 * x ^ 2 + 518921850000 * ( 1 - x ) ^ 2 ) ) 0         (1)
        From the definition field of √
         204269700 * x ^ 2 + 518921850000 * ( 1 - x ) ^ 2 ≥ 0        (2 )
        From the definition field of divisor
         sqrt ( 204269700 * x ^ 2 + 518921850000 * ( 1 - x ) ^ 2 ) ≠ 0        (3 )
        From the definition field of √
         204269700 * x ^ 2 + 518921850000 * ( 1 - x ) ^ 2 ≥ 0        (4 )
        From the definition field of divisor
         sqrt ( 204269700 * x ^ 2 + 518921850000 * ( 1 - x ) ^ 2 ) ≠ 0        (5 )

    From inequality(1)：
         x ≥ 0.95281
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(3)：
         x ∈ R （R为全体实数），即在实数范围内，不等式恒成立！
    From inequality(4)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(5)：
         x ∈ R （R为全体实数），即在实数范围内，不等式恒成立！

    From inequalities (1) and (2)
         x ≥ 0.95281    (6)
    From inequalities (3) and (6)
         x ≥ 0.95281    (7)
    From inequalities (4) and (7)
         x ≥ 0.95281    (8)
    From inequalities (5) and (8)
         x ≥ 0.95281    (9)

---

    The final solution set is :
         x ≥ 0.95281
