    作业：求算式 155×(0.5+0.42+0.34+0.26)+1/2×52.7×9.2×0.46+1/2×59.033×0.22×4.4 的值.
    题型：数学计算
    解:
          155×(0.5+0.42+0.34+0.26)+1/2×52.7×9.2×0.46+1/2×59.033×0.22×4.4
        =155×1.52+1/2×52.7×9.2×0.46+1/2×59.033×0.22×4.4
        =235.6+1/2×52.7×9.2×0.46+1/2×59.033×0.22×4.4
        =235.6+0.5×52.7×9.2×0.46+1/2×59.033×0.22×4.4
        =235.6+26.35×9.2×0.46+1/2×59.033×0.22×4.4
        =235.6+242.42×0.46+1/2×59.033×0.22×4.4
        =235.6+111.5132+1/2×59.033×0.22×4.4
        =235.6+111.5132+0.5×59.033×0.22×4.4
        =235.6+111.5132+29.5165×0.22×4.4
        =235.6+111.5132+6.49363×4.4
        =235.6+111.5132+28.571972
        =347.1132+28.571972
        =375.685172
    答案:155×(0.5+0.42+0.34+0.26)+1/2×52.7×9.2×0.46+1/2×59.033×0.22×4.4=375.685172
