3.24*5.42+6.76*4.42的简便算式,3.24*5.42+6.76*4.42的简便算式,3.24*5.42+6.76*4.42的简便算式,3.24*5.42+6.76*4.42的简便算式解

3.24*5.42+6.76*4.42的简便算式,
3.24*5.42+6.76*4.42的简便算式,

3.24*5.42+6.76*4.42的简便算式,
3.24*5.42+6.76*4.42的简便算式
解,得:
==3.24*(4.42+1)+6.76*4.42
==3.24*4.42+3.24+6.76*4.42
==(3.24*4.42+6.76*4.42)+3.24
==4.42*(3.24+6.76)+3.24
==4.42*10+3.24
==44.2+3.24
==47.44

3.24*5.42+6.76*4.42
=3.24*4.42+6.76*4.42+3.24
=(3.24+6.76)*4.42+3.24
=44.2+3.24
=47.44

原式=3.24*5.42+6.72*4.42+1*3.24=(3.24+6.72)*4.42+3.24=100*4.42+3.24=442+3.24=445.24
