Answer 1

考點(diǎn)：分?jǐn)?shù)除法,分?jǐn)?shù)乘法

專題：運(yùn)算順序及法則

分析：完成本題應(yīng)根據(jù)分?jǐn)?shù)的加、減、乘、除的運(yùn)算法則，進(jìn)行計(jì)算即可．

解答： 解：

8 9 ÷4= 2 9	1÷ 2 3 = 3 2	3 5 ÷3= 1 5	14÷ 7 15 =30	2 5 ×0.4= 4 25
3 8 ÷ 9 16 = 2 3	4 5 × 1 2 = 2 5	2 3 ÷ 1 9 =6	11 16 ÷ 11 16 =1	7× 3 14 = 3 2

點(diǎn)評(píng)：明確分?jǐn)?shù)的加、減、乘、除的運(yùn)算法則，是解答此題的關(guān)鍵．
