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
