1. (5 points) Calculate: $(3 \div 2) \times(4 \div 3) \times(5 \div 4) \times \cdots \times(2012 \div 2011) \times(2013 \div 2012)$ $=$ . $\qquad$
【Solution】Solve: $(3 \div 2) \times(4 \div 3) \times(5 \div 4) \times \cdots \times(2012 \div 2011) \times(2013 \div 2012)$
$$
\begin{array}{l}
=\frac{3}{2} \times \frac{4}{3} \times \frac{5}{4} \times \cdots \times \frac{2012}{2011} \times \frac{2013}{2012} \\
=\frac{2013}{2}
\end{array}
$$

Therefore, the answer is: $\frac{2013}{2}$.
