Question

5．直接寫(xiě)出得數(shù)     

$\frac{4}{7}$×14﹦	3.6×$\frac{4}{9}$﹦	1÷$\frac{1}{2}$﹦
$\frac{3}{4}$×$\frac{1}{8}$﹦	$\frac{5}{8}$÷$\frac{3}{8}$﹦	$\frac{1}{5}$÷3+$\frac{4}{5}$×$\frac{1}{3}$﹦

Answer 1

分析 $\frac{1}{5}$÷3+$\frac{4}{5}$×$\frac{1}{3}$先把除法變成乘法，再根據(jù)乘法分配律簡(jiǎn)算；其它題目根據(jù)分?jǐn)?shù)乘除法的計(jì)算法則求解．

解答 解：

$\frac{4}{7}$×14﹦8	3.6×$\frac{4}{9}$﹦1.6	1÷$\frac{1}{2}$﹦2
$\frac{3}{4}$×$\frac{1}{8}$﹦$\frac{3}{32}$	$\frac{5}{8}$÷$\frac{3}{8}$﹦$\frac{5}{3}$	$\frac{1}{5}$÷3+$\frac{4}{5}$×$\frac{1}{3}$﹦$\frac{1}{3}$

點(diǎn)評(píng) 本題考查了簡(jiǎn)單的分?jǐn)?shù)乘除法的計(jì)算，計(jì)算時(shí)要細(xì)心，注意把結(jié)果化成最簡(jiǎn)分?jǐn)?shù)．
