0.42×3.14=	$\frac{7}{8}$-0.75=	13÷$\frac{13}{12}$=	$\frac{1}{2}$-$\frac{3}{10}$=
1÷$\frac{1}{2}$-$\frac{1}{2}$÷1=	$\frac{1}{5}$×$\frac{1}{6}$÷$\frac{1}{5}$×$\frac{1}{6}$=

Answer 1

分析 本題根據(jù)分?jǐn)?shù)除法、小數(shù)乘法、分?jǐn)?shù)的四則混合運(yùn)算、分?jǐn)?shù)加法及減法的運(yùn)算法則計(jì)算即可；

解答 解：

$\frac{5}{26}$÷$\frac{10}{13}$=$\frac{1}{4}$	$\frac{4}{5}$×25%=0.2	0.01×40=0.4	0÷$\frac{3}{5}$+$\frac{3}{5}$=$\frac{3}{5}$
0.42×3.14=0.5024	$\frac{7}{8}$-0.75=$\frac{1}{8}$	13÷$\frac{13}{12}$=12	$\frac{1}{2}$-$\frac{3}{10}$=$\frac{1}{5}$
1÷$\frac{1}{2}$-$\frac{1}{2}$÷1=1$\frac{1}{2}$	$\frac{1}{5}$×$\frac{1}{6}$÷$\frac{1}{5}$×$\frac{1}{6}$=$\frac{1}{36}$

點(diǎn)評(píng) 考查了分?jǐn)?shù)四則運(yùn)算，小數(shù)乘法．完成本題要細(xì)心，關(guān)鍵是熟練掌握計(jì)算法則正確進(jìn)行計(jì)算．
