巧算 38.3×7.6+11×9.25+427×0.24
巧算 38.3×7.6+11×9.25+427×0.24
38.3×7.6+11×9.25+427×0.24
＝38.3×7.6+42.7×2.4+11×9.25
＝38.3×7.6+38.3×2.4+4.4×2.4+11×9.25
＝38.3×（7.6+2.4）+11×0.96+11×9.25
＝383+（10+1）×10.21
＝383+102.1+10.21
＝495.31
何必呢~用计算器哦~
原式=383×0.76+11×9.25+427×0.24
=383×0.76+427×0.24+11×9.25
=810+11×9.25
=810+(10+1)×9.25
=810+92.5+9.25
=911.75
383*0.76+427*0.24+11*9.25=810+92.5+9.25=911.75
原式=383×0.76+11×9.25+427×0.24
=383+0.24×(427-383)+11×9.25
=383+0.24×44+11×9.25
=383+10.56+(10+1)×9.25
=393.56+92.5+9.25
=495.31
