12.5×0.32×2.5简便计算

12.5×0.32×2.5简便计算 12.5×0.32×2.5 =12.5*0.8*0.4*2.5 =10*1 =10

一首歌是个居委会

12.5x0.32x0.5 =12.5x0.8x0.4x0.5 =10x0.2 =2

0.32×2.5×12.5 =(0.4×2.5)×(0.8×12.5) =1×10 =10

12.5×0.32 =12.5×0.08×4 =1×4 =4

2.5*4*8*12.5=10*100=1000

1.5×0.32×12.5 =(1.5×0.4)×(0.8×12.5) =0.6×10 =6

12.5×0.32×0.5=25×0.32×2.5×0.5=10

12.5×(4×8)×25 =(12.5×8)×25×4

0.32乘12.5乘2.5=0.4乘0.8乘12.5乘2.5=(0.4乘2.5)乘(0.8乘12.5)=1乘10=10
