2．直接寫得

$\frac{1}{5}$×$\frac{6}{125}$=	$\frac{6}{81}$÷$\frac{5}{8}$=	$\frac{7}{9}$×$\frac{7}{65}$=	$\frac{5}{54}$÷$\frac{2}{17}$=	4-4×$\frac{1}{2}$=
$\frac{3}{5}$×$\frac{4}{125}$=	$\frac{9}{81}$÷$\frac{5}{12}$=	$\frac{17}{9}$×$\frac{71}{65}$=	$\frac{5}{4}$÷$\frac{21}{17}$=	$\frac{3}{8}$×0÷5=

Answer 1

分析 根據(jù)小數(shù)、分數(shù)減法、乘除法運算的計算法則計算即可求解．

解答 解：

$\frac{1}{5}$×$\frac{6}{125}$=$\frac{6}{625}$	$\frac{6}{81}$÷$\frac{5}{8}$=$\frac{24}{135}$	$\frac{7}{9}$×$\frac{7}{65}$=$\frac{49}{585}$	$\frac{5}{54}$÷$\frac{2}{17}$=$\frac{85}{108}$	4-4×$\frac{1}{2}$=2
$\frac{3}{5}$×$\frac{4}{125}$=$\frac{12}{625}$	$\frac{9}{81}$÷$\frac{5}{12}$=$\frac{4}{15}$	$\frac{17}{9}$×$\frac{71}{65}$=$\frac{1207}{585}$	$\frac{5}{4}$÷$\frac{21}{17}$=$\frac{85}{84}$	$\frac{3}{8}$×0÷5=0

點評 考查了小數(shù)、分數(shù)減法、乘除法運算，關鍵是熟練掌握計算法則正確進行計算．
