2. $24÷\frac{3}{5}=24×(\quad)$ $\frac{3}{4}÷12=\frac{3}{4}×(\quad)$
$=(\quad)$ $=(\quad)$
$\frac{5}{6}÷\frac{3}{4}=(\quad)×(\quad)$ $\frac{8}{15}÷\frac{4}{5}=(\quad)×(\quad)$
$=(\quad)$ $=(\quad)$

答案

$\frac{5}{3}$，40；$\frac{1}{12}$，$\frac{1}{16}$；$\frac{5}{6}$，$\frac{4}{3}$，$\frac{10}{9}$；$\frac{8}{15}$，$\frac{5}{4}$，$\frac{2}{3}$

解析

$24÷\frac{3}{5}=24×\frac{5}{3}=40$；$\frac{3}{4}÷12=\frac{3}{4}×\frac{1}{12}=\frac{1}{16}$
$\frac{5}{6}÷\frac{3}{4}=\frac{5}{6}×\frac{4}{3}=\frac{10}{9}$；$\frac{8}{15}÷\frac{4}{5}=\frac{8}{15}×\frac{5}{4}=\frac{2}{3}$
3. 计算。
$\frac{2}{3}÷\frac{3}{4}$ $\frac{4}{9}÷\frac{2}{3}$ $\frac{7}{8}÷\frac{7}{16}$
$\frac{8}{9}÷\frac{20}{81}$ $12÷\frac{1}{13}$ $15÷25$

答案

$​=\frac {2}{3}×\frac {4}{3}​$
$​=\frac {8}{9}​$
$​=\frac {4}{9}×\frac {3}{2}​$
$​=\frac {2}{3}​$
$​=\frac {7}{8}×\frac {16}{7}​$
​=2​
$​=\frac {8}{9}×\frac {21}{20}​$
$​=\frac {18}{5}​$
=12×13
=156
$​=15×\frac 1{25}​$
$​=\frac 35​$
4. 解方程。
$8x=\frac{2}{5}$         $\frac{1}{3}x=\frac{7}{12}$         $\frac{5}{6}x=15$         $\frac{5}{14}x=5$

答案

$\begin {aligned}解:8x&=\frac {2}{5}\\x &=\frac {1}{20}\end {aligned}$
$\begin {aligned}解: \frac {1}{3}x&=\frac {7}{12}\\x &=\frac {7}{4}\end {aligned}$
$\begin {aligned}解: \frac {5}{6}x&=15\\x &=18\end {aligned}$
$\begin {aligned}解:\frac {5}{14}x&=5\\x &=14\end {aligned}$
