〖1/1算式〗
    作业：求算式 1/12×(0.75)^2×((2×2.4+0.7)*((32+29.7)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.7)×2.4) 的值.
    题型：数学计算
    解:
          1/12×(0.75)^2×((2×2.4+0.7)*((32+29.7)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.7)×2.4)
        =1/12×0.75^2×((2×2.4+0.7)*((32+29.7)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.7)×2.4)
        =1/12×0.75^2×(5.5*((32+29.7)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.7)×2.4)
        =1/12×0.75^2×(5.5*(61.7-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.7)×2.4)
        =1/12×0.75^2×(5.5*(61.7-174.72/(2.8×2.4))+(32-29.7)×2.4)
        =1/12×0.75^2×(5.5*(61.7-174.72/6.72)+(32-29.7)×2.4)
        =1/12×0.75^2×(5.5*35.7+(32-29.7)×2.4)
        =1/12×0.75^2×(5.5*35.7+2.3×2.4)
        =1/12×0.75^2×201.87
        =1/12×0.5625×201.87
        =0.083333×0.5625×201.87
        =0.046875×201.87
        =9.462656
    答案:1/12×(0.75)^2×((2×2.4+0.7)*((32+29.7)-(2×2.8×2.4×0.5×26)/(2.8×2.4))+(32-29.7)×2.4)=9.462656
