简便计算:7.65*72.5+7.65+76.5*2.65
简便计算:7.65*72.5+7.65+76.5*2.65

简便计算:7.65*72.5+7.65+76.5*2.65
7.65*72.5+7.65+76.5*2.65
=7.65*72.5+7.65*1+7.65*26.5
=7.65*(72.5+1+26.5)
=7.65*(72.5+27.5)
=7.65*100
=765

7.65*72.5+7.65+76.5*26.5
=76.5*(72.5+1+26.5)
=76.5*100
=7650

7.65*72.5+7.65+76.5*2.65
=7.65*72.5+7.65+7.65*26.5
=7.65*(72.5+1+26.5)
=765

=7.65*72.5+7.65*1+7.65*26.5
=7.65*(72.5+1+26.5)
=7.65*100
=765
