[1/1 Formula]
    Work: Calculate the value of equation (200×(1300)^2/2+(1500-200)×(110)^2/2+(6.667-1)×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926) .
    Question type: Mathematical calculation
    Solution:
          (200×(1300)^2/2+(1500-200)×(110)^2/2+(6.667-1)×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926)
        =(200×1300^2/2+(1500-200)×(110)^2/2+(6.667-1)×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926)
        =(200×1300^2/2+1300×(110)^2/2+(6.667-1)×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926)
        =(200×1300^2/2+1300×110^2/2+(6.667-1)×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926)
        =(200×1300^2/2+1300×110^2/2+5.667×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926)
        =211312902.228/(200×1300+(1500-200)×110+(6.667-1)×4926)
        =211312902.228/(200×1300+1300×110+(6.667-1)×4926)
        =211312902.228/(200×1300+1300×110+5.667×4926)
        =211312902.228/430915.642
        =490.381136

    Answer:(200×(1300)^2/2+(1500-200)×(110)^2/2+(6.667-1)×4926×1234)/(200×1300+(1500-200)×110+(6.667-1)×4926)=490.381136
