[1/1 Formula]
    Work: Calculate the value of equation 155×(0.5+0.42+0.34+0.26)+1/2×52.7×9.2×0.46+1/2×52.7×0.22×4.4 .
    Question type: Mathematical calculation
    Solution:
          155×(0.5+0.42+0.34+0.26)+1/2×52.7×9.2×0.46+1/2×52.7×0.22×4.4
        =155×1.52+1/2×52.7×9.2×0.46+1/2×52.7×0.22×4.4
        =235.6+1/2×52.7×9.2×0.46+1/2×52.7×0.22×4.4
        =235.6+0.5×52.7×9.2×0.46+1/2×52.7×0.22×4.4
        =235.6+26.35×9.2×0.46+1/2×52.7×0.22×4.4
        =235.6+242.42×0.46+1/2×52.7×0.22×4.4
        =235.6+111.5132+1/2×52.7×0.22×4.4
        =235.6+111.5132+0.5×52.7×0.22×4.4
        =235.6+111.5132+26.35×0.22×4.4
        =235.6+111.5132+5.797×4.4
        =235.6+111.5132+25.5068
        =347.1132+25.5068
        =372.62

    Answer:155×(0.5+0.42+0.34+0.26)+1/2×52.7×9.2×0.46+1/2×52.7×0.22×4.4=372.62
