    SAT math question about percentages

    Percents are a very easy way to express fractions as parts of a whole. Basically, a percent is a fraction whose denominator is 100. When you see a percent, you know that it represents a fraction of 100, which makes it easy to understand.

    The equation, 0.30x = 90, may be used to solve the problem. Dividing both sides of the equation by 0.30 gives x = 300.

    Hope these help!!
