Question

10．直接寫得數(shù)

$\frac{4}{5}$×2=	$\frac{3}{4}$×0.6=	6×$\frac{2}{9}$=	$\frac{3}{4}$×$\frac{7}{6}$×0=
0.625×$\frac{4}{15}$=	$\frac{1}{6}$+$\frac{5}{6}$×$\frac{1}{5}$=	$\frac{1}{4}$÷$\frac{4}{5}$=	$\frac{3}{16}$÷3=

Answer 1

分析 根據(jù)分?jǐn)?shù)、小數(shù)四則運算的計算法則進(jìn)行計算即可，$\frac{1}{6}$+$\frac{5}{6}$×$\frac{1}{5}$先算乘法再算加法．

解答 解：

$\frac{4}{5}$×2=$\frac{8}{5}$	$\frac{3}{4}$×0.6=$\frac{9}{20}$	6×$\frac{2}{9}$=$\frac{4}{3}$	$\frac{3}{4}$×$\frac{7}{6}$×0=0
0.625×$\frac{4}{15}$=$\frac{1}{6}$	$\frac{1}{6}$+$\frac{5}{6}$×$\frac{1}{5}$=$\frac{1}{3}$	$\frac{1}{4}$÷$\frac{4}{5}$=$\frac{5}{16}$	$\frac{3}{16}$÷3=$\frac{1}{16}$

點評 此題考查了分?jǐn)?shù)、小數(shù)四則運算的計算法則的運用．
