[ 1/1Inequality]
    Assignment:Find the solution set of inequality x ≤4／x ≥6 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
         x ≤4 / x         (1)
        4 / x ≥6         (2)
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         x ≤ -2 或  0 ≤ x ≤ 2
    From inequality(2)：
         0 ≤ x ≤ 2/3
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         0 ≤ x ≤ 2/3    (4)
    From inequalities (3) and (4)
         0 < x ≤ 2/3     (5)

---

    The final solution set is :
         0 < x ≤ 2/3
