0.23x519+234x0.481简便运算

Answer 1

解:可以将234运用乘法分配律化为0.234ⅹ1000，那么234ⅹ0.481就变为0.234x481，再将0.234运用拆分法分解为(0.23+0.004)分别乘以481，则234x0.481变为0.23ⅹ481+0.004ⅹ481，然后提取0.23，按四则运算法则进行计算。计算过程
0.23ⅹ519+234ⅹ0.481
=0.23ⅹ519+0.23ⅹ481+0.004ⅹ481
=0.23ⅹ(519+481)+0.004ⅹ481
=0.23ⅹ1000+1.924
=230+1.924
=231.924。

Answer 2

0.234x529+234x0.481
=234x（0.529+0.481）
=234x100+234x0.01
=23402.34
以上为计算简便过程
