Question

0.108×99+1.08×0.1,简便运算？

Answer 1

0.108×99+1.08×0.1
=0.108×（100-1）+1.08×0.1
=10.8-0.108+0.108
=10.8

Answer 2

0.108×99+1.08×0.1
=0.108×(10×9.9) +1.08×0.1
=0.108×10×9.9+1.08×0.1
=1.08×9.9+1.08×0.1
=1.08×(9.9+0.1)
=1.08×10
=10.8

Answer 3

0.108×99+1.08×0.1可以通过运用分配律和结合律进行简便运算，具体如下：

0.108×99+1.08×0.1 = (0.108×100 - 0.108) + (1.08×0.1)
= 10.8 - 0.108 + 0.108
= 10.8

因此，0.108×99+1.08×0.1等于10.8。

Answer 4

把99拆分成9.9×10
原式=0.108×10×9.9+1.08×0.1
=1.08×9.9+1.08×0.1
=1.08×(9.9+0.1)
=1.08×10
=10.8

Answer 5

1.08*（9.9+0.1）
