Foster is centering a photo that is 3 1/2 inches wide on a scrapbook page that is 12 inches wide.How far form each side of the page should he put the pic in
To solve, subtract 12 from 3 1/2 to get the total open space (width left) on the page. Then divide by two because there are two sides that need to have equal space. You get 4.25 inches
