[ 1/1Inequality]
    Assignment:Find the solution set of inequality （0.51×33680x+0.51×28000）÷（16420x+13600） <（0.49×33680+0.49+28000）÷（17440x+14400） .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 0.51 × 33680 * x + 0.51 × 28000 ) ÷ ( 16420 * x + 13600 ) < ( 0.49 × 33680 + 0.49 + 28000 ) ÷ ( 17440 * x + 14400 )         (1)

---

    From inequality(1)：
         -0.825688 < x < 1.610605

---

    The final solution set is :
         -0.825688 < x < 1.610605
