Question

12.5乘以44.4用简便运算怎么算？

Answer 1

有两种可选
第一种：12.5x44.4=12.5x4x11.1=50x11.1=555
第二种：12.5x44.4=12.5x（40+4+0.4）=500+50+5=555

Answer 2

此特殊之算题如果把乘数分拆开来算可能运算起来会简单点：
12.5×44.4
=12.5×40+12.5×4+12.5×0.4
=500+50+5
=555
计算结果是555，我的回答希望你喜欢。

Answer 3

12.5*44.4
=12.5*(40+4+0.4)
=12.5*40+12.5*4+12.5*0.4
=500+50+5
=555

Answer 4

12.5*（40+4+0.4）
12.5*40+12.5*4+12.5*0.4
500+50+5
555

Answer 5

12.5×44.4
