Question

16．請(qǐng)你直接填出下面各題的得數(shù)．

$\frac{5}{8}$×$\frac{4}{15}$=	$\frac{5}{6}$÷8=	$\frac{9}{14}$÷$\frac{5}{8}$=	$\frac{1}{3}$÷$\frac{1}{6}$=	$\frac{1}{5}$÷2÷$\frac{1}{5}$=
0÷$\frac{13}{14}$=	$\frac{1}{3}$÷$\frac{3}{10}$=	$\frac{1}{4}$×7=	$\frac{1}{2}$+$\frac{3}{8}$=	$\frac{1}{4}$×3÷$\frac{1}{4}$×3=

Answer 1

分析 根據(jù)分?jǐn)?shù)四則運(yùn)算的計(jì)算法則進(jìn)行計(jì)算即可，$\frac{1}{5}$÷2÷$\frac{1}{5}$和$\frac{1}{4}$×3÷$\frac{1}{4}$×3運(yùn)用乘法交換律簡(jiǎn)算即可．

解答 解：

$\frac{5}{8}$×$\frac{4}{15}$=$\frac{1}{6}$	$\frac{5}{6}$÷8=$\frac{5}{48}$	$\frac{9}{14}$÷$\frac{5}{8}$=$\frac{36}{35}$	$\frac{1}{3}$÷$\frac{1}{6}$=2	$\frac{1}{5}$÷2÷$\frac{1}{5}$=$\frac{1}{2}$
0÷$\frac{13}{14}$=0	$\frac{1}{3}$÷$\frac{3}{10}$=$\frac{10}{9}$	$\frac{1}{4}$×7=$\frac{7}{4}$	$\frac{1}{2}$+$\frac{3}{8}$=$\frac{7}{8}$	$\frac{1}{4}$×3÷$\frac{1}{4}$×3=9

點(diǎn)評(píng) 此題考查了分?jǐn)?shù)四則運(yùn)算的計(jì)算法則的運(yùn)用．
