[ 1/1Inequality]
    Assignment:Find the solution set of inequality -0.3 <(x-28)/28 <0.3 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -0.3 < ( x - 28 ) / 28         (1)
         ( x - 28 ) / 28 <0.3         (2)

---

    From inequality(1)：
         x ＞ 98/5
    From inequality(2)：
         x < 182/5

---

    From inequalities (1) and (2)
         98/5 < x < 182/5     (3)

---

    The final solution set is :
         98/5 < x < 182/5
