("In the 1980s, A&W tried to compete with the immensely popular McDonald’s Quarter Pounder by offering a bigger, juicier ⅓ Pound Burger at the same price. Unfortunately, Americans aren’t so great at math. Confused consumers wrongly assumed that ¼ was bigger than ⅓ (You know, because 4 is bigger than 3) and the whole experiment went down in history as a huge marketing fail.").
