A percent is expression a fraction when the denominator is equal to 100. The word "percent" means "per 100". A typical problem might ask that 6 is what percentage of 12. In order to solve this, we need to set up a proportion, where we solve for the numerator of the fraction, which we will then circle as the percentage for our final answer. To solve these problems, we will also learn to solve equations and use the rules of algebra to find the final answer.
