Question

11．直接寫(xiě)出得數(shù)．

$\frac{1}{6}$+3=	$\frac{1}{3}$-$\frac{1}{4}$=
1÷$\frac{6}{7}$=	$\frac{8}{9}$×$\frac{1}{8}$=
50%×0.2÷10%=	$\frac{8}{9}$÷$\frac{4}{3}$=
$\frac{5}{3}$×$\frac{4}{5}$=	10-2.7=
$\frac{7}{8}$÷$\frac{7}{16}$×2=	$\frac{1}{5}$+$\frac{4}{5}$÷2=

Answer 1

分析 根據(jù)分?jǐn)?shù)和小數(shù)加減乘除法的計(jì)算方法進(jìn)行計(jì)算．

解答 解：

$\frac{1}{6}$+3=3$\frac{1}{6}$	$\frac{1}{3}$-$\frac{1}{4}$=$\frac{1}{12}$
1÷$\frac{6}{7}$=$\frac{7}{6}$	$\frac{8}{9}$×$\frac{1}{8}$=$\frac{1}{9}$
50%×0.2÷10%=1	$\frac{8}{9}$÷$\frac{4}{3}$=$\frac{1}{3}$
$\frac{5}{3}$×$\frac{4}{5}$=$\frac{4}{3}$	10-2.7=7.3
$\frac{7}{8}$÷$\frac{7}{16}$×2=4	$\frac{1}{5}$+$\frac{4}{5}$÷2=$\frac{3}{5}$

點(diǎn)評(píng) 口算時(shí)，注意運(yùn)算符號(hào)和數(shù)據(jù)，然后再進(jìn)一步計(jì)算．
