Question

3.68ⅹ99+36.8简便方法？

Answer 1

原式子=3.68×99+3.68×10
=3.68×（99+10）
=3.68×109
=401.12
这运用到了结合律。

Answer 2

=3.68*(99+10)
=3.68*(110-1)
=3.68*(100+10-1)
=3.68*100+3.68*10-3.68
=368+36.8-3.68
=401.12
运用乘法分配律来简便算法

Answer 3

=3.68 * (99 + 10) = 3.68 * (110-1) = 3.68 * (100 + 10-1) = 3.68 * 100 + 3.68 * 10-3.68 = 368 + 36.8-3.68 = 401.12 use the multiplication distribution law to simplify the algorithm

Answer 4

=3.68 * (99 + 10) = 3.68 * (110-1) = 3.68 * (100 + 10-1) = 3.68 * 100 + 3.68 * 10-3.68 = 368 + 36.8-3.68 = 401.12 use the multiplication distribution law to simplify the algorithm

Answer 5

家纺前面的算式是两个数的乘法，后边这个数可以看作是一与36.8的乘积，然后就可以提取公因式36.8，括号里面剩下的加法就是99+1，正好得到100，最后计算36.8和100的乘积，得到答案3680。
