Best ResponseYou've already chosen the best response.4Here are the steps to follow: Find the Least Common Multiple of the denominators (which is called the Least Common Denominator). Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator. Then add (or subtract) the fractions, as you wish!
