Question

6.5x0.09+0.65x6.4-6.5x0.54怎么计算？

Answer 1

解：计算过程如下
6.5×0.09+0.65×6.4-6.5×0.54
=6.5×0.09+6.5×0.64-6.5×0.54
=6.5×0.09+6.5×（0.64-0.54）
=6.5×0.09+6.5×0.1
=0.585+0.65
=1.235

Answer 2

6.5×0.09+0.65×6.4—6.5×0.54
=6.5×0.09+6.5×0.1×6.4—6.5×0.54
=6.5×(0.09+0.64—0.54)
=6.5×(0.73—0.54)
=6.5×0.09
=6.5×(0.1—0.01)
=6.5×0.1—6.5×0.01
=0.65—0.065
=0.585

Answer 3

6.5×0.09+0.65×6.4—6.5×0.54
=6.5×0.09+6.5×0.1×6.4—6.5×0.54
=6.5×(0.09+0.64—0.54)
=6.5×｛0.09+（0.64-0.54)｝
=6.5×0.19
=6.5×(0.2—0.01)
=6.5×0.2—6.5×0.01
=1.3—0.065
=1.235

Answer 4

6.5*0.09+0.65*6.4-6.5*0.54
=6.5*0.09+6.5*0.64-6.5*0.54
=6.5*(0.09+0.64-0.54)
=6.5*0.19
=0.65*1.9
=0.65*(2-0.1)
=1.3-0.065
=1.235

Answer 5

=6.5（0.09+0.64-0.54）=6.5×0.19=6.5×0.2-0.065=1.3-0.065=1.235
