$\frac{2}{5}$÷$\frac{1}{5}$=	$\frac{4}{5}$-$\frac{7}{10}$=	12÷$\frac{1}{7}$×0=	2+$\frac{3}{5}$=
$\frac{4}{9}$×$\frac{3}{8}$=	$\frac{1}{5}$+$\frac{5}{6}$+$\frac{4}{5}$=

Answer 1

分析 根據(jù)分?jǐn)?shù)加減法、分?jǐn)?shù)乘除法的計(jì)算方法進(jìn)行解答即可得到答案．

解答 解：

2-$\frac{1}{6}$=1$\frac{5}{6}$	$\frac{2}{5}$+$\frac{1}{2}$=$\frac{9}{10}$	1÷$\frac{2}{9}$=$\frac{9}{2}$	$\frac{6}{13}$×26=12
$\frac{2}{5}$÷$\frac{1}{5}$=2	$\frac{4}{5}$-$\frac{7}{10}$=$\frac{1}{10}$	12÷$\frac{1}{7}$×0=0	2+$\frac{3}{5}$=2$\frac{3}{5}$
$\frac{4}{9}$×$\frac{3}{8}$=$\frac{1}{6}$	$\frac{1}{5}$+$\frac{5}{6}$+$\frac{4}{5}$=1$\frac{5}{6}$

點(diǎn)評(píng) 此題主要考查的是分?jǐn)?shù)加減法、分?jǐn)?shù)乘除法的計(jì)算方法的應(yīng)用．
