Question

0.96╳6.9用简便计算？

Answer 1

0.96×6.9
=（1-0.04）×（7-0.1）
=7-1×0.1-0.04×7+0.04×0.1
=7-0.1-0.28+0.004
=6.9-0.28+0.004
=6.62+0.004
=6.624
那么我们可以通过上面的简便计算过程运算得到答案是6.624

追答

0.96×6.9
=（1-0.04）×（7-0.1）
=7-0.1-0.28+0.004
=7-0.376
=6.624
那么，可以通过简便计算得到6.624

Answer 2

0.96╳6.9用简便计算，可以吧，0.96变成1-0点04，然后分别乘以，6.9，在相减。0.96×0.69＝（1一0.04）x0.69＝0.69-0.69*0.04＝0.69-0.0276＝0.6624

Answer 3

解：0.96×6.9=0.96×(7-0.1)=0.96×7-0.96×0.1=6.72-0.096=6.72-(0.1-0.004)=6.72-0.1+0.004=6.82+0.004=6.824，运用乘法分配率逆运算和加法结合律逆运算，希望可以帮到你

Answer 4

0.96x6.9=6.9x(1-0.04)=6.9-0.276=6.624

Answer 5

0.96X6.9
=（1-0.04）X6.9
=1X6.9-0.04x6.9
=6.9-0.276
=6.624
