%282%2F3%29A-%283%2F4%29A=%283%2F4%29A
%282%2F3+-3%2F4%29A+=+%283%2F4%29+A........eliminate A on both sides
%28%282%2A4-3%2A3%29%2F12%29=%283%2F4%29%29
%28%288-9%29%2F12%29=%283%2F4%29%29
%28%28-1%29%2F12%29=%283%2F4%29%29...........both sides multiply by 12
%28%28-1%2912%2F12%29=12%283%2F4%29%29...........
%28-1%29=3%2A3%29...........
