    Assignment:Find the solution set of inequality (x/27)/（x/27+（1-x）*4.2/244.661） <0.464 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x / 27 ) / ( x / 27 + ( 1 - x ) * 4.2 / 244.661 ) <0.464         (1)
        From the definition field of divisor
         x / 27 + ( 1 - x ) * 4.2 / 244.661 ≠ 0        (2 )

---

    From inequality(1)：
         -0.863928 < x < 0.286345
    From inequality(2)：
         x < -0.863928 或  x ＞ -0.863928

---

    From inequalities (1) and (2)
         -0.863928 < x < 0.286345     (3)

---

    The final solution set is :
         -0.863928 < x < 0.286345
