Question

直接寫(xiě)得數(shù) 4.7+2.5=	2.5×4=	6.3÷0.2=	2.4÷0.08=
9-0.22=	10÷0.4=	0.5×4÷0.5×4=	6.5-5.6=
0×12.5=	5.6÷8=	3.5×0.2=	4.2÷0.14=
23.7÷1=	1×9.9=	2.8÷0.4=	9.7-3.4=
10÷0.4=

Answer 1

考點(diǎn)：小數(shù)乘法,小數(shù)除法

專(zhuān)題：運(yùn)算順序及法則

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

解答：

解：4.7+2.5=7.2	2.5×4=10	6.3÷0.2=31.5	2.4÷0.08=30
9-0.22=8.78	10÷0.4=25	0.5×4÷0.5×4=16	6.5-5.6=0.9
0×12.5=0	5.6÷8=0.7	3.5×0.2=0.7	4.2÷0.14=30
23.7÷1=23.7	1×9.9=9.9	2.8÷0.4=7	9.7-3.4=6.3
10÷0.4=25

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．
