Answer 1

考點(diǎn)：分?jǐn)?shù)的加法和減法,分?jǐn)?shù)乘法,分?jǐn)?shù)除法

專題：計(jì)算題

分析：根據(jù)分?jǐn)?shù)加、減、乘、除法的計(jì)算方法和小數(shù)除法的計(jì)方法進(jìn)行計(jì)算即可．

解答：

解： 6- 2 3 =5 1 3	7 4 ÷ 4 7 = 49 16	3 8 × 16 9 = 2 3	3 4 + 1 4 ×4=1 3 4	（ 1 4 + 1 8 ）×4=1 1 2
7 8 ÷ 8 7 = 49 64	3 4 × 3 5 = 9 20	34÷0.2=170	7× 1 7 ÷7× 1 7 = 1 49	0÷ 2 3 + 7 10 = 7 10

點(diǎn)評(píng)：本題考查了學(xué)生基本的計(jì)算能力，在計(jì)算時(shí)要細(xì)心．
