1- 1 2 - 1 4 =	1 5 - 1 8 + 4 5 =	3 5 + 1 6 + 5 6 =	3- 1 5 =

Answer 1

考點(diǎn)：分?jǐn)?shù)的加法和減法

專題：運(yùn)算順序及法則

分析：根據(jù)分?jǐn)?shù)加減法的計(jì)算方法和小數(shù)乘法的計(jì)算方法進(jìn)行計(jì)算．

解答：

解： 9 10 - 4 5 = 1 10	0.8×12.5=10	3 4 - 3 8 = 3 8	1 2 - 1 3 = 1 6
1- 1 2 - 1 4 = 1 4	1 5 - 1 8 + 4 5 = 7 8	3 5 + 1 6 + 5 6 = 8 5	3- 1 5 = 14 5

點(diǎn)評(píng)：本題考查了學(xué)生基本的計(jì)算能力．
