简算0.25*40.4+0.125*10.8

简算0.25*40.4+0.125*10.8
0.25*40.4+0.125*10.8
=0.25*(40+.04)+0.125*(10+0.8)
=0.25*40+0.25*0.4+0.125*10+0.125*0.8
=10+0.1+1.25+0.1
=11.45

0.25*40.4+0.125*10.8
=0.25*(40+0.4)+0.125*(10+0.8)
=10+0.1+1.25+0.1
=11.45

原试=
=0.25*(40+.04)+0.125*(10+0.8)
=0.25*40+0.25*0.4+0.125*10+0.125*0.8
=10+0.1+1.25+0.1
