14.2*1.25+1.25*0.5+5.3*1.25简算
14.2*1.25+1.25*0.5+5.3*1.25简算

14.2*1.25+1.25*0.5+5.3*1.25简算
14.2×1.25 + 1.25×0.5 + 5.3×1.25
= 1.25×(14.2 + 0.5 + 5.3)
= 1.25×20
= 25

14.2*1.25+1.25*0.5+5.3*1.25
=1.25(14.2+0.5+5.3)
=1.25*20
=25

14.2*1.25+1.25*0.5+5.3*1.25=1.25*(14.2+0.5+5.3)=1.25*20=25

=(14.2+0.5+5.3)*1.25
=20*1.25
=25
