Answer 1

考點(diǎn)：小數(shù)乘法,小數(shù)的加法和減法,小數(shù)除法,小數(shù)四則混合運(yùn)算

專(zhuān)題：計(jì)算題

分析：根據(jù)四則運(yùn)算的計(jì)算法則計(jì)算即可求解．

解答： 解：

0.8×0.5=0.4	6.4÷8=0.8	7.82×0=0	7.4×0.1=0.74
8.1÷0.3=27	6.2×0.3=1.86	6.6÷1.1=6	5.7+3=8.7
7.8÷1.3=6	8×12.5=100	10÷0.2=50	45÷4.5=10
10-0.78=9.22	2.3×100=230	4×0.05=0.2	0.8÷0.8×0.1=0.1
5.6+4.4÷2=7.8	3.3-3.3÷3=2.2

點(diǎn)評(píng)：考查了四則運(yùn)算，關(guān)鍵是熟練掌握計(jì)算法則正確進(jìn)行計(jì)算．
