Answer 1

考点：分数的加法和减法,分数乘法

专题：运算顺序及法则

分析：直接利用分数四则计算的计算法则和混合运算的运算顺序计算得出答案即可．

解答：

解： 2 5 + 3 5 =1	1 6 ÷ 1 2 = 1 3	8- 3 4 =7 1 4	6× 1 3 =2
8 11 ÷ 8 9 = 9 11	5 8 - 1 2 = 1 8	2 3 × 3 4 = 1 2	3 5 + 1 2 = 11 10
6 7 ÷3= 2 7	2 5 × 1 4 = 1 10	1 6 + 5 6 × 1 5 = 1 3	7 8 ×4× 8 7 =4
9 8 ×0=0	7 8 ÷ 7 10 = 5 4	4 3 ×75%=1	7 8 - 3 4 = 1 8

点评：掌握计算法则是关键，注意计算结果的化简．
