（能简算的要简便计算要过程）6-3/11-8/1111/14-3/5+3/14-2/5 3/4-(2/5-1/4)
6-3/11-8/11
=6-(3/11+8/11)
=6-1
=5
11/14-3/5+3/14-2/5
=11/14+3/14-(2/5+3/5)
=1-1
=0
3/4-(2/5-1/4)
= 3/4+1/4-2/5
=1-2/5
=3/5
要采纳最先回答的正确答案,是对答题者劳动的尊重.祝进步!

11/14-3/5+3/14-2/5
=(11/14+3/14)-(3/5+2/5)
=1-1
=0

3/4-(2/5-1/4)
=3/4-2/5+1/4
=(3/4+1/4)-2/5
=1-2/5
=3/5
