Question

6．直接寫得數(shù)．

$\frac{1}{3}$×0=	$\frac{1}{4}$×$\frac{2}{5}$=	$\frac{5}{6}$×1.2=	$\frac{7}{12}$×$\frac{3}{14}$=	0.45×$\frac{3}{5}$=
9×$\frac{7}{18}$=	$\frac{2}{3}$×$\frac{9}{10}$=	$\frac{4}{25}$×100=	18×$\frac{1}{6}$=	$\frac{4}{11}$×$\frac{11}{4}$=

Answer 1

分析 根據(jù)分?jǐn)?shù)乘法的計(jì)算方法，依次進(jìn)行計(jì)算即可．

解答 解：

$\frac{1}{3}$×0=0	$\frac{1}{4}$×$\frac{2}{5}$=$\frac{1}{10}$	$\frac{5}{6}$×1.2=1	$\frac{7}{12}$×$\frac{3}{14}$=$\frac{1}{8}$	0.45×$\frac{3}{5}$=0.27
9×$\frac{7}{18}$=$\frac{7}{2}$	$\frac{2}{3}$×$\frac{9}{10}$=$\frac{3}{5}$	$\frac{4}{25}$×100=16	18×$\frac{1}{6}$=3	$\frac{4}{11}$×$\frac{11}{4}$=1

點(diǎn)評(píng) 此題考查了分?jǐn)?shù)乘法，明確分?jǐn)?shù)乘法的計(jì)算方法，是解答此題的關(guān)鍵．
