Explanation:

When adding fractions, you first need a common denominator. 37and79 do not have the same denominator, but both 7 and 9 can go into 63.
So,
37⋅99=2763and79⋅77=4963. Now they have common denominators, and are still equal to the original fractions because they were multiplied by what equals to 1. 77=1,99=1.

Now, we simply put them side by side and add up the numerators. You do not add the denominators.
2763+4963=7663

You can now convert to proper fractions.
