To add fractions, you need to have a common denominator.
First, find the least common multiple (LCM) of 6 and 7, which is 42.
Now, convert both fractions to have the same denominator of 42:
(5/6) * (7/7) = 35/42
(6/7) * (6/6) = 36/42
Now, you can add the fractions:
35/42 + 36/42 = (35 + 36)/42 = 71/42
The fraction 71/42 cannot be simplified any further, so that is the final answer.
