Last week, Molly decided to get her favorite photograph enlarged to make a poster. When she got the poster enlarged, there was a mark on it. The mark, which had length of 1/6 ft. and width 1/9 ft., came from a mark on the photograph that had length 1/4 in. and width 1/6 in. Find the ratio of the length of the mark on the photograph in inches to the length of the mark on the poster in inches. Use pencil and paper. Find the ratio using feet instead. Is the result the same? Explain.
