[ 1/1Inequality]
    Assignment:Find the solution set of inequality k+10-6000k^2/(90k-10) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         k + 10 - 6000 * k ^ 2 / ( 90 * k - 10 ) >0         (1)
        From the definition field of divisor
         90 * x - 10 ≠ 0        (2 )

---

    From inequality(1)：
         k < 0.111111
    From inequality(2)：
         k < 1/9 或  k ＞ 1/9

---

    From inequalities (1) and (2)
         k < 0.111111    (3)

---

    The final solution set is :
         k < 0.111111
