This was inspired by the excellent sketches from David Cox and Dan Pearcy on fraction multiplication and addition. Be sure to try them![br]David's fraction addition http://www.geogebratube.org/material/show/id/21313[br]and his fraction multiplication: http://www.geogebratube.org/material/show/id/21396[br]Dan's fraction addition http://www.geogebratube.org/material/show/id/21639[br][br][br]The sketch shows you a fraction and 3 part-whole comparisons.[br]Which is closest to the real fraction?
