计算．

8÷ 4 5 =	5÷ 10 11 =	14÷ 7 9 =	6÷ 2 7 =
3 11 ÷ 3 8 =	3 5 ÷ 3 7 =	8 27 ÷ 2 9 =	5 8 ÷ 3 7 =

Answer 1

分析：分数除法的计算法则：除以一个不为零的数等于乘上这个数的倒数．

解答：解：

8÷ 4 5 =10	5÷ 10 11 = 11 2	14÷ 7 9 =18	6÷ 2 7 =21
3 11 ÷ 3 8 = 8 11	3 5 ÷ 3 7 = 7 5	8 27 ÷ 2 9 = 4 3	5 8 ÷ 3 7 = 35 24

点评：本题考查了简单的分数除法的计算，计算时要细心，注意把结果化成最简分数．
