0.75乘4.75加4又4分之3加4又4分之3乘4.25等于几

0.75乘4.75加4又4分之3加4又4分之3乘4.25等于几
0.75乘4.75加4又4分之3加4又4分之3乘4.25等于几

0.75乘4.75加4又4分之3加4又4分之3乘4.25等于几
0.75乘4.75加4又4分之3加4又4分之3乘4.25
=0.75×4.75+4.75+4.75×4.25
=4.75×﹙0.75+1+4.25)
=4.75×6
=28.5

原式=4.75×﹙0.75+1+4.25)=4.75×6=28.5

0.75 ×4.75+4.75(4又4分之3=4.75)+4.75×4.25
原式=4.75×(0.75+4.25+1)
=4.75×6
=28.5
