51.2×8.1+11×9.25+537×0.19的简便运算
51.2×8.1+11×9.25+537×0.19的简便运算
51.2×8.1+11×9.25+537×0.19
=512×0.81+537×(1-0.81)+11×9.25
=537-0.81×(537-512)+11×9.25
=537-0.81×25+11×(9+0.25)
=537-0.81×25+99+0.11×25
=(537+99)+25×(0.11-0.81)
=(537+100-1)-25×0.7
=636-17.5
=618.5
51.2*8.1+11*9.25+537*0.19 =512+25*0.19+11*0.25+99 =512+0.25*(19+11)+99 =512+99+0.25*30 =611+7.5 =618.5
