0.65×6.4+0.64×5.4简便计算

0.65×6.4+0.64×5.4简便计算
0.65×6.4+0.64×5.4简便计算

0.65×6.4+0.64×5.4简便计算
0.65×6.4+0.64×5.4
=0.64×6.4+0.64×3.6+0.01×6.4+1.8×0.64
=0.64(6.4+3.6)+0.064+1.152
=6.4+1,216
=7.616

0.65×6.4+0.64×5.4
=6.5×0.64+0.64×5.4
=0.64×(6.5+5.4)
=0.64×11.9
=7.616

=0.64x(6.5+5.4)
=0.64x10
=6.4

0.65*6.4+0.64*5.4
= 0.65*6.4+6.4*0.54
=(0.65+0.54)*6.4
=1.19*6.4
=7.616

=6.5×0.64+5.4×0.64
=0.64×11.9=7.616
