[ 1/1Inequality]
    Assignment:Find the solution set of inequality (2m-2)/(3m+3) <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 2 * m - 2 ) / ( 3 * m + 3 ) <0         (1)
        From the definition field of divisor
         3 * x + 3 ≠ 0        (2 )

---

    From inequality(1)：
         -1 < m < 1
    From inequality(2)：
         m < -1 或  m ＞ -1

---

    From inequalities (1) and (2)
         -1 < m < 1     (3)

---

    The final solution set is :
         -1 < m < 1
