    Assignment:Find the solution set of inequality 0.40 <0.605/1+y% <0.50 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0.40 <0.605 / 1 + y %         (1)
        0.605 / 1 + y % <0.50         (2)

---

    From inequality(1)：
         y ＞ -41/2
    From inequality(2)：
         y < -21/2

---

    From inequalities (1) and (2)
         -41/2 < y < -21/2     (3)

---

    The final solution set is :
         -41/2 < y < -21/2
