2.64×0.9+0.264的简便运算
2.64×0.9+0.264的简便运算
2.64×0.9+0.264的简便运算
=2.64×0.9+2.64×0.1
=2.64×(0.9+0.1)
=2.64×1
=2.64
2.64(0.9+0.1)
=2.64
原式=2.64*0.9+2.64*0.1
=2.64*(0.9+0.1)
=2.64
2.64×0.9+0.264
=2.64*0.09+2.64
=2.64*1.09
=0.264*10*0.9+0.264
同时乘以十,合并同类项,再除以十
0.264×<9+1>=2.64
解:原式=2.64x0.9+0.1x2.64=(0.9+0.1)x2.64=2.64
