There's nothing more to do from here.
The fractions have different denominators, so the first step is to find a common denominator.
The least common multiple of 8 and 9 is 72.
We now need to find equivalent fractions for each of the two fractions with 72 as the denominator.
The first fraction, 78 is equivalent to 6372
The second fraction, 49 is equivalent to 3272
We now have the two fractions expressed over a common denominator, so we can add the numerators
6372+3272=63+3272
which gives 9572
This is in the simplest form, so we are finished.
