$\Large{\color{#20A900}{\dfrac{9!}{8!!}}} \div {\color{#EC7300}{\dfrac{7!}{6!!}}} = \, ?$

Notation:

$n!! = \begin{cases} n \times (n-2) \times \cdots \times 5 \times 3 \times 1 && \text{if } n \text{ is odd;} \\ n \times (n-2) \times \cdots \times 6 \times 4 \times 2 && \text{if } n \text{ is even;} \\ 1 && \text{if } n = 0, - 1. \\ \end{cases}$
