[ 1/1Inequality]
    Assignment:Find the solution set of inequality -0.2 <(x-43.2)/43.2 <0.2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        -0.2 < ( x - 43.2 ) / 43.2         (1)
         ( x - 43.2 ) / 43.2 <0.2         (2)

---

    From inequality(1)：
         x ＞ 864/25
    From inequality(2)：
         x < 1296/25

---

    From inequalities (1) and (2)
         864/25 < x < 1296/25     (3)

---

    The final solution set is :
         864/25 < x < 1296/25
