[ 1/1Inequality]
    Assignment:Find the solution set of inequality 13 <10*(14+12x)/2.4/7.5 <14 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        13 <10 * ( 14 + 12 * x ) / 2.4 / 7.5         (1)
        10 * ( 14 + 12 * x ) / 2.4 / 7.5 <14         (2)

---

    From inequality(1)：
         x ＞ 47/60
    From inequality(2)：
         x < 14/15

---

    From inequalities (1) and (2)
         47/60 < x < 14/15     (3)

---

    The final solution set is :
         47/60 < x < 14/15
