How much of a candy bar is left after "x" of the bar have been eaten?

Answer

First, we must be able to understand the question. The question asks us to identify what fraction of a candy bar remains after a fraction of it has been eaten. The question is missing numbers, represented by the percent symbol. Assuming the question intended to ask about fractions, if 2/5 of the bar was eaten, we can find out how much is left by subtracting the eaten portion from the whole bar. A whole bar can be represented as 1, or as 5/5 if we use the same denominator as the fraction given. So, 5/5 - 2/5 = 3/5. Thus, 3/5 of the bar is left. If 1/2 of the bar was eaten, then 1 - 1/2 = 1/2 of the bar is left.
