4.5乘0.9加0.45乘11怎样简算?

4.5乘0.9加0.45乘11怎样简算?
4.5×0.9+0.45×11
=4.5×0.9+4.5×1.1
=（0.9+1.1）×4.5
=2×4.5
=9

=4.5×0.9+4.5×1.1
=4.5×（0.9+1.1）
=4.5×2
=9

4.5*0.9+0.45*11
=4.5*0.9+4.5*1.1
=4.5*(0.9+1.1)
=9

4.5*0.9+0.45*11 =0.45*9+0.45*11 =0.45*(9+11) =0.45*20=9

4.5×0.9+0.45×11
=0.45×(10×0.9)+0.45×11
=0.45×9+0.45×11
=0.45×(9+11)
=0.45×20
=4.5×2
=9
