12.5x(80+0.8)简便运算如下 12.5x(80+0.8) =12.5x80+12.5x8 =1000+10 =1010

=12.5×0.8×0.96 =10×0.96 =9.6

12.5×0.8×0.96

12.5x75x0.8简便计算 12.5x75x0.8 =12.5*0.8*75 =10*75 =750

3.6X12.5X0.8÷36 =(12.5X0.8)X3.6÷36 =10X0.1 =1

35.8×12.5×0.8 =35.8×100 =3580

12.5x0.8+1.25x0.8-1.25 =1.25×8+1.28+0.8-1.25 =1.25×(8-0.8-1) =1.25×8.2 =1.25×8+1.25×0.2 =10+0.5 =10.5

1.25×0.8+1.25×0.8-1.25 =1.25×(0.8+0.8-1) =1.25×0.6 =0.75
