    Assignment:Find the solution set of inequality 0.9% <（135.6-X）/（125.6-X） <1% .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0.9 % < ( 135.6 - x ) / ( 125.6 - x )         (1)
         ( 135.6 - x ) / ( 125.6 - x ) <1 %         (2)
        From the definition field of divisor
         125.6 - x ≠ 0        (3 )

---

    From inequality(1)：
         x < 125.6 或  x ＞ 135.690817
    From inequality(2)：
         125.6 < x < 67172/495
    From inequality(3)：
         x < 628/5 或  x ＞ 628/5

---

    From inequalities (1) and (2)
         135.690817 < x < 67172/495     (4)
    From inequalities (3) and (4)
         135.690817 < x < 67172/495     (5)

---

    The final solution set is :
         135.690817 < x < 67172/495
