[ 1/1Inequality]
    Assignment:Find the solution set of inequality 4.5*10000/(1+4.5*10000*x) >= 5*10000/(1+5*10000*x)*0.999 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        4.5 * 10000 / ( 1 + 4.5 * 10000 * x ) >= 5 * 10000 / ( 1 + 5 * 10000 * x ) * 0.999         (1)
        From the definition field of divisor
         1 + 4.5 * 10000 * x ≠ 0        (2 )
        From the definition field of divisor
         1 + 5 * 10000 * x ≠ 0        (3 )

    From inequality(1):
         x ≥ 11/5000
    From inequality(2):
         x < -0.000022 或  x > -0.000022
    From inequality(3):
         x < -1/50000 或  x > -1/50000

    From inequalities (1) and (2)
         x ≥ 11/5000    (4)
    From inequalities (3) and (4)
         x ≥ 11/5000    (5)

    The final solution set is :

         x ≥ 11/5000
