Assuming you meant negative six and one-half divided by negative two-thirds: (-6 + 1/2) / (-2/3)
$${\frac{\left({\mathtt{\,-\,}}{\mathtt{6}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}{{\mathtt{\,-\,}}\left({\frac{{\mathtt{2}}}{{\mathtt{3}}}}\right)}} = {\frac{{\mathtt{33}}}{{\mathtt{4}}}} = {\mathtt{8.25}}$$
