    Assignment:Find the solution set of inequality 300/(300+0.775x) >(300/(300+x))*1.4 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        300 / ( 300 + 0.775 * x ) > ( 300 / ( 300 + x ) ) * 1.4         (1)
        From the definition field of divisor
         300 + 0.775 * x ≠ 0        (2 )
        From the definition field of divisor
         300 + x ≠ 0        (3 )

---

    From inequality(1)：
         x ＞ -387.096774
    From inequality(2)：
         x < -387.096774 或  x ＞ -387.096774
    From inequality(3)：
         x < -300 或  x ＞ -300

---

    From inequalities (1) and (2)
         x ＞ -387.096774    (4)
    From inequalities (3) and (4)
         -387.096774 < x < -300 或  x ＞ -300    (5)

---

    The final solution set is :
         -387.096774 < x < -300 或  x ＞ -300
