〖1/1算式〗
    作业：求算式 1/12×(0.85)^2×((2×2.8+2.4)*(60.6-(2×2.8×2.4×0.5×26)/(2.8×2.4))+7.3×2.8) 的值.
    题型：数学计算
    解:
          1/12×(0.85)^2×((2×2.8+2.4)*(60.6-(2×2.8×2.4×0.5×26)/(2.8×2.4))+7.3×2.8)
        =1/12×0.85^2×((2×2.8+2.4)*(60.6-(2×2.8×2.4×0.5×26)/(2.8×2.4))+7.3×2.8)
        =1/12×0.85^2×(8*(60.6-(2×2.8×2.4×0.5×26)/(2.8×2.4))+7.3×2.8)
        =1/12×0.85^2×(8*(60.6-174.72/(2.8×2.4))+7.3×2.8)
        =1/12×0.85^2×(8*(60.6-174.72/6.72)+7.3×2.8)
        =1/12×0.85^2×(8*34.6+7.3×2.8)
        =1/12×0.85^2×297.24
        =1/12×0.7225×297.24
        =0.083333×0.7225×297.24
        =0.060208×297.24
        =17.896226
    答案:1/12×(0.85)^2×((2×2.8+2.4)*(60.6-(2×2.8×2.4×0.5×26)/(2.8×2.4))+7.3×2.8)=17.896226
