[ 1/2Inequality]
    Assignment:Find the solution set of inequality abs(1.5*x) <0.25 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         abs ( 1.5 * x ) <0.25         (1)

---

    From inequality(1)：
         -1/6 < x < 1/6

---

    The final solution set is :
         -1/6 < x < 1/6
[ 2/2Inequality]
    Assignment:Find the solution set of inequality abs(-0.25*x-1.5*x) <0.25 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         abs ( -0.25 * x - 1.5 * x ) <0.25         (1)

---

    From inequality(1)：
         -1/7 < x < 1/7

---

    The final solution set is :
         -1/7 < x < 1/7
