a printer wants to center a 6inch wide column of text on a page that is 8.5inch wide. if the margins on the two sides are even, how wide should each margin be?
the answer is 1.25 in. If you take 8.5 in and subtract the 6 in column you get 2.5 inches left, then you divide that by two and get 1.25 in on each side.
