6.25*0.16+264*0.0625+5.24*6.25+0.625*20的简便计算
6.25*0.16+264*0.0625+5.24*6.25+0.625*20
=6.25*0.16+2.64*6.25+5.24*6.25+6.25*2
=6.25*(0.16+2.64+5.24+2)
=6.25*10.04
=6.25*(10+0.04)
=6.25*10+6.25*0.04
=62.5+0.25
=62.75
原式=6.25*0.16+5.24*6.25+264*0.0625+0.625*20
=6.25*5.4+264*0.0625+0.625*20
=0.625*5.4*10+264*.0625*0.1+.0625*20
=0.625*(54+26.4+20)
=5/8*100.4
=62.75
不知道对不对,好像也挺麻烦的。
