[ 1/1Inequality]
    Assignment:Find the solution set of inequality {(a+1)/[1*(a+1)+0.73]}/{a/[(1*a)+0.73]} >1.04 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( a + 1 ) / ( 1 * ( a + 1 ) + 0.73 ) ) / ( a / ( ( 1 * a ) + 0.73 ) ) >1.04         (1)
        From the definition field of divisor
         1 * ( x + 1 ) + 0.73 ≠ 0        (2 )
        From the definition field of divisor
         ( 1 * x ) + 0.73 ≠ 0        (3 )
        From the definition field of divisor
         x / ( ( 1 * x ) + 0.73 ) ≠ 0        (4 )

    From inequality(1)：
         -5.223695 < a < -1.73 或  0 < a < 3.493695
    From inequality(2)：
         a < -173/100 或  a ＞ -173/100
    From inequality(3)：
         a < -73/100 或  a ＞ -73/100
    From inequality(4)：
         a < -0.73 或  -0.73 < a < 0 或  a ＞ 0

---

    From inequalities (1) and (2)
         -5.223695 < a < -1.73 或  0 < a < 3.493695     (5)
    From inequalities (3) and (5)
         -5.223695 < a < -1.73 或  0 < a < 3.493695     (6)
    From inequalities (4) and (6)
         -5.223695 < a < -1.73 或  0 < a < 3.493695     (7)

---

    The final solution set is :
         -5.223695 < a < -1.73 或  0 < a < 3.493695
