3.2乘以2.4加上32乘以0.76简便运算怎么做3.2乘以2.4加上32乘以0.76简便运算怎么做3.2乘以2.4加上32乘以0.76简便运算怎么做3.2*2.4+32*0.76=3.2*【2.4+

3.2乘以2.4加上32乘以0.76简便运算怎么做
3.2乘以2.4加上32乘以0.76简便运算怎么做

3.2乘以2.4加上32乘以0.76简便运算怎么做
3.2*2.4+32*0.76=3.2*【2.4+10*0.76】=3.2*【2.4+7.6】=3.2*10=32

32×(0,24+0,76)=32

=3.2×2.4+3.2×7.6=3.2x(2.4+7.6)=3.2×10=32

=32×0.24+32×0.76=32x(0.24+0.76)=32

把32乘以0.76看成3.2×7.6,7.6+2.4=10才简便
3.2乘以2.4加上32乘以0.76
=3.2×(2.4+7.6)
=32
