really looks like

%28-1%2F2%29%288%2F4%29%2812%2F1%29


Multiply the numerators and the denominators separately
%28-1%2A8%2A12%29%2F%282%2A4%2A1%29

%28-1%2A8%2A12%29%2F%288%29 Multiply the denominator

%28-1%2Across%288%29%2A12%29%2Fcross%288%29 Cancel like terms

-12%2F1 Simplify

-1%2F12 Now take the reciprocal
