    题型：数学计算
    解:
          (18.69×(1.78/3+15.1+2.9)+2077.84×(15.1/3×(2×35.68+239.53)/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44)))/2378.73
        =(18.69×18.593333+2077.84×(15.1/3×(2×35.68+239.53)/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44)))/2378.73
        =(18.69×18.593333+2077.84×(15.1/3×310.89/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44)))/2378.73
        =(18.69×18.593333+2077.84×(15.1/3×310.89/275.21+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44)))/2378.73
        =(18.69×18.593333+2077.84×8.585887+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44)))/2378.73
        =(18.69×18.593333+2077.84×8.585887+282.18×(2.29/3×361.46/(115.01+131.44)))/2378.73
        =(18.69×18.593333+2077.84×8.585887+282.18×(2.29/3×361.46/246.45))/2378.73
        =(18.69×18.593333+2077.84×8.585887+282.18×1.119555)/2378.73
        =18503.524868/2378.73
        =7.778741
    答案:(18.69×(1.78/3+15.1+2.9)+2077.84×(15.1/3×(2×35.68+239.53)/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44)))/2378.73=7.778741
