A candy bar company uses equivalent fractions when producing different-sized
candy bars. If the super size candy bar is twice as big as the normal size,
then all of the ingredients will be doubled. For example, if 1.5/5 of the normal
size candy bar is caramel, then 3/10 of the super size candy bar is caramel.
That means a 10 ounce candy bar will contain 3 ounces of caramel.
