One way to eliminate fractions in solving equations is to clear the denominator- you multiply all terms on both sides of the equation by the least common multiple, or common denominator of all of the fractions involved. Here we have only one fraction, so we multiply all terms by the denominator. Alternatively, you could use this same idea to multiply an equation with decimals by a power of ten to make no more decimals. Just be sure to multiply all terms on both sides of the equation by whatever you have chosen!
