%284-3%2Fy%29%2F8

Since there is one fraction make everything else a fraction,
by putting 1's underneath:

%284%2F1-3%2Fy%29%2F%288%2F1%29

Then the LCD of all denominators is y

Multiply top and bottom by y, written as y%2F1

%28%28y%2F1%29%284%2F1-3%2Fy%29%29%2F%28%28y%2F1%29%288%2F1%29%29

%284y%2F1-3y%2Fy%29%2F%288y%2F1%29
