62.5*0.16+2640*0.0625+5.2*6.25+0.0625*20
62.5*0.16+2640*0.0625+5.2*6.25+0.0625*20

62.5*0.16+2640*0.0625+5.2*6.25+0.0625*20
这道题你要提公因式才好解 也最简单
那么原式=6.25*1.6+6.25*26.4+6.25*5.2+6.25*0.2
=6.25*(1.6+26.4+5.2+0.2)
=6.25*33.4=208.75

208.7500

62.5*0.16+2640*0.0625+5.2*6.25+0.0625*20
=62.5*(0.16+2.64+0.52+0.02)
=62.5*3.34
=208.75

208.75
