简算 6.25*0.16+264*0.0625+5.2*6.25+0.625*20 是怎样算的?
6.25*0.16+264*0.0625+5.2*6.25+0.625*20
=6.25*0.16+264*0.01*6.25+5.2*6.25+6.25*0.1*20
=6.25*0.16+2.64*6.25+5.2*6.25+6.25*2
=6.25*(0.16+2.64+5.2+2)
=6.25*10
=62.5

原式=6.25x0.16+6.25x2.64+6.25x5.2+6.25x2=6.25x(0.16+2.64+5.2+2)=6.25x10=62.5

=6.25*(0.16+2.64+5.2+2)
=6.25*10
=62.5
