[1/1 Formula]
    Work: Calculate the value of equation (18.71×7.7×18.40+25×(-56.6))/(20.34×(6.3+7.7)) .
    Question type: Mathematical calculation
    Solution:
          (18.71×7.7×18.40+25×(-56.6))/(20.34×(6.3+7.7))
        =(18.71×7.7×18.40+25×(-56.6))/(20.34×(6.3+7.7))
        =1235.8328/(20.34×(6.3+7.7))
        =1235.8328/(20.34×14)
        =1235.8328/284.76
        =4.33991

    Answer:(18.71×7.7×18.40+25×(-56.6))/(20.34×(6.3+7.7))=4.33991
