[ 1/1Inequality]
    Assignment:Find the solution set of inequality (0.447+0.5x)/(x+1) >0.45 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 0.447 + 0.5 * x ) / ( x + 1 ) >0.45         (1)
        From the definition field of divisor
         x + 1 ≠ 0        (2 )

---

    From inequality(1)：
         x < -1 或  x ＞ 3/50
    From inequality(2)：
         x < -1 或  x ＞ -1

---

    From inequalities (1) and (2)
         x < -1 或  x ＞ 3/50    (3)

---

    The final solution set is :
         x < -1 或  x ＞ 3/50
