Ensure that the denominators are the same when adding or subtracting fractions.

If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.
You multiply the fractions until the denominators are equal. Then, you subtract.
