Question

10.1×3.26-0.326的简便计算？

Answer 1

因为10.1×3.26=101×0.326，所以原式等于101×0.326-0.326运用乘法分配律逆运算就是0.326×（101-1）=32.6

Answer 2

3.26和0.326差10bei4，可以凑成相同的数。10.1×3.26-0.326=10.1×3.26-0.1×3.26=（10.1-0.1）×3.26=10×3.26=32.6

Answer 3

36.26×10.1-0.1×3.26 =36.26×（10+0.1）-0.326 =36.26×10+36.26×0.1-0.326 =362.6+3.626-0.326 =362.6+(3.626-0.326)=362.6+3.3 =365.9

Answer 4

提取公约数，把3.26提出来得

3.26x(10.1-0.1)
=3.26x10
=32.6

Answer 5

刻意将0.326变成0.1x3.26，然后就用10.1-0.1得到10x3.26=32.6
