四减十一分之五加五分之十一减十一分之六简便运算？

Answer 1

4-5/11+11/5-6/11应用加法交换律结合律简便运算
=4+11/5-（6/11+5/11）
=4+11/5-1
=（4-1）+11/5
=3+11/5
=15/5+11/5
=26/5

Answer 2

解：
4－5／11+11/5-6/11
＝4－（5/11+6/11）＋2又1／5
＝4－1＋2又1／5
＝3＋2又1／5
＝5又1／5

Answer 3

4-5/11+11/5-6/11
=4+11/5-6/11-5/11
=4+11/5-（6/11+5/11）
=4+11/5-1
=（4-1）+11/5
=3-2又1/2
=1/2

Answer 4

4-5/11+11/5-6/11
=4+11/5-6/11-5/11
=4+11/5-（6/11+5/11）
=4+11/5-1
=（4-1）+11/5
=3+11/5
=15/5+11/5
=26/5
=5.2
