    Assignment:Find the solution set of inequality 103.9 ≤301.88739622581132196226113208392/x <104.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        103.9 ≤301.88739622581132196226113208392 / x         (1)
        301.88739622581132196226113208392 / x <104.2         (2)
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         0 ≤ x ≤ 2.905557
    From inequality(2)：
         x < 0 或  x ＞ 2.897192
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         2.897192 < x ≤ 2.905557     (4)
    From inequalities (3) and (4)
         2.897192 < x ≤ 2.905557     (5)

---

    The final solution set is :
         2.897192 < x ≤ 2.905557
