If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator.

Now with all the fractions with the same denominator, add together the numerators.

Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.
