10.625*2005+2005*8分之3-2005

10.625*2005+2005*8分之3-2005
10.625*2005+2005*8分之3-2005
=2005*(10.625+3/8-1)
=2005*10
=20050

10.625*2005+2005*8分之3-2005
=2005*(10.625+3/8-1)
=2005*10
=20050

10.625 × 2005 + 2005 × 3 / 8 - 2005
= (10 + 0.625)× 2005 + 2005 × 0.375 - 2005
= (10 + 0.625 + 0.375 - 1)× 2005
= (10 + 1 - 1)× 2005
= 10 × 2005
= 20050
