0.47 0.5x0.8简便计算

0.47x0.5x0.8 =0.47*(0.5x0.8)=0.47*0.4=0.188

0.47X0.5X0.8=0.47X(0.5X0.8)=0.47X0.4=1.88

0.47x0.5x0.8=0.47*0.4=0.188乘法结合律

0.4x0.5x0.8=0.4x(0.5x0.8)=0.4x0.4=0.16

0.47*0.5*0.8=0.47*(0.5*0.8)=0.47*0.4=0.188

0.47*(0.5*0.8)=0.47*0.4=0.188

0.47*(0.5*0.8)=0.47*0.4=0.188

0.47x0.5x0.8=0.47*0.4=0.188乘法结合律

0.47*0.5*0.8=0.47*(0.5*0.8)=0.47*0.4=0.188

=0.47*(0.5*0.8)=0.47*0.4=0.188
