Answer 1

考点：分数除法,分数乘法

专题：运算顺序及法则

分析：根据分数乘法、分数除法、分数加法和分数减法的计算方法，依次进行解答即可．

解答： 解：

6÷ 3 8 =16	3 4 ÷ 4 5 = 15 16	5 6 ÷10= 1 12	3 7 + 3 7 = 6 7	3 4 × 5 7 = 15 28
0.4÷ 1 10 =4	2-1  3 8 = 5 8	9 11 ÷ 3 4 = 12 11	3 4 - 3 4 =0	20÷ 1 4 =80
5 13 ×39=15	0÷ 3 5 =0	1× 5 7 = 5 7	5 7 × 5 7 = 25 49	4 9 ÷ 4 9 =1
3 7 × 5 6 = 5 14	7 45 ÷35= 1 225	7 11 × 22 63 = 2 9	1 6 + 1 3 = 1 2	3 5 ÷1= 3 5
2÷ 2 3 =3	9 35 ÷ 9 11 = 11 35	1÷ 5 6 = 6 5	8- 1 4 =7 3 4	9 25 ×100=36

点评：明确分数乘法、分数除法、分数加法和分数减法的计算方法，是解答此题的关键．
