    Assignment:Find the solution set of inequality （S-1.8）/S >0.55 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( S - 1.8 ) / S >0.55         (1)
        From the definition field of divisor
        x ≠ 0        (2 )

---

    From inequality(1)：
         S < 0 或  S ＞ 4
    From inequality(2)：
         S < 0 或  S ＞ 0

---

    From inequalities (1) and (2)
         S < 0 或  S ＞ 4    (3)

---

    The final solution set is :
         S < 0 或  S ＞ 4
