    The usual way around is to find the lowest common multiple of the denominators. In this case, the LCM of 2 and 4 is 4. Then, you change the fractions so that they are on the same denominator.





    Once the denominators are the same, you perform the calculation with the numerators, that is:



    Subtraction is similar. You only change the sign, like this:
