Question

5/14与1/7的和，加上6/11与1/22的差和是多少？

Answer 1

分数脱式计算5/14+1/7+6/11-1/22
解题思路：四则运算规则（按顺序计算、先算乘除后算加减，有括号先算括号，有乘方先算乘方）即脱式运算（递等式计算）需在该原则前提下进行
解题过程：

(5/14+1/7)+(6/11-1/22)

=(5/14+2/14)+(12/22-1/22)

=1/2+1/2

=1

存疑请追问，满意请采纳

Answer 2

（5/14+1/7）+（6/11-1/22）
=5/14+2/14+12/22-1/22
=7/14+11/22
=1/2+1/2
=1
5/14与1/7的和，加上6/11与1/22的差和是1。

Answer 3

=5/14+2/14+(6/11-1/22)
=7/14+12/22-1/22
=1/2+11/22
=1
