Answer 1

考點(diǎn)：分?jǐn)?shù)乘法,分?jǐn)?shù)除法

專題：運(yùn)算順序及法則

分析：運(yùn)用分?jǐn)?shù)的乘除法的計(jì)算法則來求解．

解答：

解： 3 14 × 7 8 = 3 16	3÷ 1 3 =9	6 7 × 1 4 = 3 14	0÷ 5 14 =0	1 7 ×4÷ 1 7 ×4=16
5 8 ÷4= 5 32	3 4 - 3 8 = 3 8	4 9 × 1 3 = 4 27	4 5 ÷ 5 4 = 16 25	0.33=0.027

點(diǎn)評：本題主要考查學(xué)生對分?jǐn)?shù)乘除法的計(jì)算法則的掌握情況．
