Question

0.023×0.5+0.5×0.77用简便方法怎么算？

Answer 1

0.023*0.5+0.5*0.77
=0.5*(0.023+0.77)
=0.5*0.793
=0.5*(0.8-0.007)
=0.4-0.0035
=0.3965

Answer 2

0.23÷10×0.5+0.5×0.77
=（0.23+0.77）×0.5÷10
=1×0.5÷10
=0.5÷10
=0.05

Answer 3

如果真是要用简便方法的题，那你题目中肯定有一个数字的小数点点错了位置。请检查更正后再来提问。
我列出一种可能如下：
0.23×0.5+0.5×0.77
=（0.23+0.77）×0.5
= 1×0.5
= 0.5

Answer 4

=(0.023+0.77)×1/2
=0.793÷2
=0.3965

Answer 5

0.023+0.77=0.793
0.793/2=0.3965
