Answer 1

考点：分数乘法,分数除法

专题：计算题

分析：根据分数乘除法的计算方法进行计算．

解答： 解：

6 7 × 5 9 = 10 21	5 18 ×3= 5 6	5 26 × 3 20 = 3 104	6 7 ÷4= 3 14
1× 7 9 = 7 9	0× 5 13 =0	17× 2 51 = 2 3	3 4 ÷ 7 8 = 6 7
8 21 × 7 16 = 1 6	2 3 ÷14= 1 21	26× 12 13 =24	14 13 ÷28= 1 26
5 8 × 1 5 = 1 8	2 3 ×24=16	9 5 ÷ 3 10 =6	5 8 ÷ 5 3 = 3 8

点评：口算时，注意运算符号和数据，然后再进一步计算．
