拜托，简便运算怎么没给过程的？这确实是小学五年级试卷上的简便运算题目，我也晕啊！请高手解答！

Answer 1

1.原题= 8.02-90.1÷17
=8.02-5.3
=2.72
2. 原题=20.28÷(0.4×1.3)
=20.28÷0.52
=39
3. 原题=20.48÷0.8×0.9
=25.6×0.9
=23.04
4. 原题=10.8÷9÷5+35.8
=1.2÷5+35.8
=0.24+35.8
=36.04

Answer 2

8.02-90.1÷17
=8.02-5.3
=2.72

20.28÷(0.4×1.3)
=20.28÷0.52
=39

20.48÷0.8×0.9
=25.6×0.9
=23.04

10.8÷9÷5+35.8
=1.2÷5+35.8
=0.24+35.8
=36.04
这里的“.”是小数点，“/”是除号~~~~

Answer 3

8.02-9.01/1.7 = 2.72
20.28/0.4/1.3 = 39
20.48*0.9/0.8 = 23.04
10.8/45+35.8 = 36.04

Answer 4

1.=8.02-5.3
=2.72
2.=20.28÷0.52
=39
3.=25.6×0.9
=23.04
4.=1.2÷5+35.8
=0.24+35.8
=36.04
