[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1.2×(3600/2x)+0.5×(3600/x) ≤400000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1.2 × ( 3600 / 2 * x ) + 0.5 × ( 3600 / x ) ≤400000         (1)
        From the definition field of divisor
        x ≠ 0        (2 )

---

    From inequality(1)：
         x ≤ 185.180685
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         x < 0 或  0 < x ≤ 185.180685     (3)

---

    The final solution set is :
         x < 0 或  0 < x ≤ 185.180685
