                    ADDITION AND SUBTRACTION OF UNLIKE FRACTIONS:

                    In addition, and subtraction of unlike fractions, we first convert them into
                    corresponding equivalent like fractions and then they are added or subtracted.

                    STEP 1: Obtain the fractions and their denominators.
                                                               STEP 2: Find the LCM (least common
                                                               multiple) of the denominators.
                                                               STEP 3: Convert each fraction into an
                                                               equivalent fraction having its
                                                               denominator equal to the LCM (least
                                                               common multiple) obtained in Step II.

                                                               STEP 4: Add or subtract like fractions
                                                               obtained in Step III.

                                                               STEP 5: Reduce the fraction to simplest
                                                               form if possible.
