1. 列竖式计算。
$3.6 × 2.2 = $ $2.6 × 4.3 = $ $16.8 ÷ 2.4 = $

$\begin{array}{r}× \\\hline\end{array}\\\hline $ $\begin{array}{r}× \\\hline\end{array}\\\hline $ $\begin{array}{r}\enclose{longdiv}{}\end{array}{} $

答案： 1.7.92 11.18 7

2. 脱式计算。
$\frac{14}{15} - (\frac{2}{3} + \frac{1}{5})$ $\frac{1}{3} + \frac{5}{6} - \frac{1}{2}$ $\frac{5}{18} + (1 - \frac{5}{6})$

答案： 2.$\frac{1}{15}$ $\frac{2}{3}$ $\frac{4}{9}$
