5/12+8/7-5/12×1/7用简便方法列竖式计算怎么做？

Answer 1

简便计算过程
解题思路：不能进行简便运算的按顺序计算，简便运算核心是运用加法和乘法各种定律进行计算，计算出整数部分方便后续计算的过程
5/12×8/7-5/12×1/7
=5/12×(8/7-1/7)
=5/12×1
=5/12
存疑请追问满意请采纳

Answer 2

5/12+8/7-5/12×1/7
＝5/12×（1-1/7）+8/7
＝5/12×6/7+8/7
＝5/14+8/7
＝5/14+16/14
＝21/14
＝3/2

Answer 3

=5/12*（8/7-1/7）
=5/12*1
=5/12

Answer 4

＝5/12*（8/7-1/7）

＝5/12*7/7

＝5/12*1

＝5/12

Answer 5

5/12+8/7-5/12×1/7
=5/12×(1-1/7)+8/7
=5/12×6/7+8/7
=5/14+16/14
=21/14
=3/2
