Nothing happens unless you make it happen.
What you need to do is to convert the given fractions into equivalent fractions - all with the same denominator. This can simply be the product (multiple) of all the denominators but it is more efficient to use their least common multiple (LCM). This is because using the LCM ensures that you will be working with the smallest numbers.
