算出来真的是天才呀！哪怕只知道两题也行啊！！！！！！
简便运算
3.6×0.76+3.6×0.24 （2/5- 2/5）÷2×5/3

15/16-（7/12+1/6）×1/2

4/5×8/11+4/5×3/11+4/5
要过程！要过程！算出来真的是天才呀！哪怕只知道两题也行啊！！！

Answer 1

36×0.76+3.6×0.24
=3.6×7.6+3.6×0.24
=3.6×（7.6+0.24）
=3.6×7.84
=...
是不是3.6×0.76+3.6×0.24
=3.6×（0.76+.024）
=3.6×1
=3.6
（2/5- 2/5）÷2×5/3

=0÷2×5/3
=0
4/5×8/11+4/5×3/11+4/5
=4/5×（8/11+3/11）+4/5
=4/5×1+4/5
=8/5
15/16-（7/12+1/6）×1/2
=15/16-(7/12+2/12)×1/2
=15/16-9/12×1/2
=15/16-3/8
=15/16-6/16
=9/16

追问

应该是
3.6×0.76+3.6×0.24
=3.6×（0.76+.024）
=3.6×1
=3.6
（2/5- 2/5）÷2×5/3
=0÷2×5/3
=0
15/16-（7/12+1/6）×1/2
=15/16-(7/12+2/12)×1/2
=15/16-9/12×1/2
=15/16-3/8
=15/16-6/16
=9/16
4/5×8/11+4/5×3/11+4/5
=4/5×（8/11+3/11）+4/5
=4/5×1+4/5
=8/5

Answer 2

1、3.6×0.76＋3.6×0.24＝3.6×﹙0.76＋0.24﹚＝3.6×1＝3.6
2、﹙2/5－2/5﹚÷2×5/3＝0÷2×5/3＝0
3、15/16－﹙7/12＋1/6﹚×1/2，这道不能简算
＝15/16－3/4×1/2
＝15/16－3/8
＝9/16
4、4/5×8/11＋4/5×3/11＋4/5＝4/5×﹙8/11＋3/11＋1﹚＝4/5×2＝8/5＝1.6
