6．直接寫出得數(shù)

$\frac{4}{5}$×10%=	$\frac{7}{8}$+85%=	60%+$\frac{2}{5}$=	1÷$\frac{2}{3}$=
$\frac{4}{9}$×$\frac{3}{8}$=	2-65%=	1-6%=	$\frac{5}{6}$÷5=
$\frac{2}{3}$÷$\frac{2}{3}$=	$\frac{3}{7}$+2=	$\frac{5}{11}$×0×$\frac{5}{11}$=	4÷$\frac{1}{2}$=
0÷$\frac{3}{4}$=	$\frac{7}{13}$×$\frac{26}{35}$=	$\frac{7}{12}$×36=	$\frac{4}{7}$+61.5%+38.5%=

Answer 1

分析 先把百分?jǐn)?shù)轉(zhuǎn)化成分?jǐn)?shù)，再根據(jù)分?jǐn)?shù)乘法、分?jǐn)?shù)除法、分?jǐn)?shù)加法計(jì)算方法進(jìn)行口算．

解答 解：

$\frac{4}{5}$×10%=$\frac{2}{25}$	$\frac{7}{8}$+85%=1.725	60%+$\frac{2}{5}$=1	1÷$\frac{2}{3}$=$1\frac{1}{2}$
$\frac{4}{9}$×$\frac{3}{8}$=$\frac{1}{6}$	2-65%=1.35	1-6%=0.94	$\frac{5}{6}$÷5=$\frac{1}{6}$
$\frac{2}{3}$÷$\frac{2}{3}$=1	$\frac{3}{7}$+2=$2\frac{3}{7}$	$\frac{5}{11}$×0×$\frac{5}{11}$=0	4÷$\frac{1}{2}$=8
0÷$\frac{3}{4}$=0	$\frac{7}{13}$×$\frac{26}{35}$=$\frac{2}{5}$	$\frac{7}{12}$×36=21	$\frac{4}{7}$+61.5%+38.5%=$1\frac{4}{7}$

點(diǎn)評(píng) 此題主要考查了分?jǐn)?shù)乘地、分?jǐn)?shù)除法、分?jǐn)?shù)加法計(jì)算方法的應(yīng)用情況．
