$0.36+9.6÷3.2$

$=0.36+3$

$=3.36$

$(\dfrac {7}{6}-\dfrac {5}{9})÷\dfrac {11}{8}$

$=\dfrac {11}{18}×\dfrac {8}{11}$

$=\dfrac {4}{9}$

$\begin {aligned}&36÷[(17.5+0.5)×8]\\=&36÷[18×8]\\=&36÷18÷8\\=&2÷8\\=&\frac {1}{4}\end {aligned}\qquad \qquad\begin {aligned}&5÷\frac {5}{7}-\frac {5}{7}×\frac {1}{5}\\=&5×\frac {7}{5}-\frac {1}{7}\\=&7-\frac {1}{7}\\=&6\frac {6}{7}\end {aligned}$

$\begin {aligned}&\frac {5}{12}×\frac {1}{5}+\frac {4}{5}×\frac {5}{12}\\=&\frac {5}{12}×(\frac {1}{5}+\frac {4}{5})\\=&\frac {5}{12}×1\\=&\frac {5}{12}\end {aligned}\qquad \qquad\begin {aligned}&(0.4+0.2)×\frac {2}{3}+\frac {5}{6}\\=&0.6×\frac {2}{3}+\frac {5}{6}\\=&\frac {2}{5}+\frac {5}{6}\\=&\frac {37}{30}\end {aligned}$

$16.5+16.5×1.6=42.9(千米)$

$(90+90×\dfrac{2}{3})×2.8=420(\mathrm{千米})$

$420＜460\quad 460-420=40(\mathrm{千米})$

不能相遇，两车相距 40 千米。

$(60-20)×\dfrac{2}{5}=16$(平方米)

$4.5×(1+\dfrac{2}{9})=5.5(小时)$
