5/9÷7+4/9×1/7的简便运算怎么算？

Answer 1

可以运用乘法分配律进行计算。
5/9÷7+4/9×1/7
=5/9×1/7+4/9×1/7
=(5/9+4/9)×1/7
=1×1/7
=1/7

Answer 2

在除法运算中，除以一个数等于乘这个数的倒数。这道题5/9÷7就相当于5/9×1/7，原式就可以改写为5/9×1/7+4/9×1/7，利用乘法分配率提取公因数1/7，就可以进行简便计算了。具体计算过程如下：
5/9÷7+4/9×1/7
=5/9×1/7+4/9×1/7
=（5/9+4/9）×1/7
=1×1/7
=1/7

Answer 3

关于5/9÷7+4/9×1/7使用简便的方法来进行操作，步骤如下：
5/9÷7+4/9×1/7
=5/9×1/7+4/9×1/7
=（5/9+4/9）×1/7
=1×1/7
=1/7

Answer 4

5/9/7+4/9x1/7的简便运算如下：
5/9/7+4/9x1/7=5/9x1/7+4/9x1/7=（5/9+4/9）x1/7=1x1/7=1/7

Answer 5
