Question

直接寫得數(shù)

7.5+3.08=	3-2.99=	3÷1.5=	6.5-3.8=	2.7-0.27=
4.2÷0.06=	6.3-0.4=	4.8÷24=	0.673×0=	1.25×8=
0.01÷0.001×0.1=	0.5×0.1÷0.5×0.1=	0.9×100÷1000=

Answer 1

考點：小數(shù)的加法和減法,小數(shù)乘法,小數(shù)除法

專題：計算題

分析：根據(jù)四則運算的計算法則計算即可求解．注意0.5×0.1÷0.5×0.1變形為（0.5÷0.5）×（0.1×0.1）計算．

解答： 解：

7.5+3.08=10.58	3-2.99=0.01	3÷1.5=2	6.5-3.8=2.7	2.7-0.27=2.43
4.2÷0.06=70	6.3-0.4=5.9	4.8÷24=0.2	0.673×0=0	1.25×8=10
0.01÷0.001×0.1=1	0.5×0.1÷0.5×0.1=0.01	0.9×100÷1000=0.09

點評：考查了四則運算，關(guān)鍵是熟練掌握計算法則正確進(jìn)行計算．
