6.4×(0.125+12.5)简便计算怎么写?
6.4×(0.125+12.5)简便计算怎么写?

6.4×(0.125+12.5)简便计算怎么写?
6.4×(0.125+12.5)
=(0.8×8)+(0.125+12.5)
=【0.8×(0.125+12.5)】×8
=【0.1+10】×8
=10.1×8
=80.8

0.8(8*0.125 8*12.5)=80.8

6.4×(0.125+12.5)
=0.8×8×0.125×(1+100)
=0.8×1×101
=80.8

6.4×(0.125+12.5)
=0.8×8×(0.125+12.5)
=0.8×(8×0.125+8×12.5)
=0.8×(1+100)
=0.8×1+0.8×100
=0.8+80
=80.8

6.4×(0.125+12.5)
=6.4×0.125+6.4×12.5
=0.8+80
=80.8

6.4×(0.125+12.5)
=0.8 ( 8*0.125+8*12.5)
=0.8 (1+100)
=0.8+80
=80.8

0.8*(8*0.125+12.5*8)=0.8*(1+10)=80.8
