直接寫得數(shù) 2.5×0.4=	1.27+8.73=	2-1$\frac{6}{7}$=	100÷50%=
$\frac{5}{6}$×$\frac{8}{15}$=	$\frac{5}{9}$-$\frac{1}{9}$×0=	8-0.18=	0.84÷0.7=

Answer 1

分析 根據(jù)小數(shù)和分?jǐn)?shù)加減乘除法運(yùn)算的計(jì)算法則計(jì)算即可求解．

解答 解：

2.5×0.4=1	1.27+8.73=10	2-1$\frac{6}{7}$=$\frac{1}{7}$	100÷50%=200
$\frac{5}{6}$×$\frac{8}{15}$=$\frac{4}{9}$	$\frac{5}{9}$-$\frac{1}{9}$×0=$\frac{5}{9}$	8-0.18=7.82	0.84÷0.7=1.2

點(diǎn)評(píng) 考查了小數(shù)和分?jǐn)?shù)加減乘除法運(yùn)算，關(guān)鍵是熟練掌握計(jì)算法則正確進(jìn)行計(jì)算．
