(3)/(9) +
(3)/(27) equals
(4)/(9).

First, simplify
(3)/(9) to
(1)/(3) and also
(3)/(27) to
(1)/(9). Your problem should look like:
(1)/(3) +
(1)/(9).
Second, find the least common denominator of
(1)/(3) and
(1)/(9) to get 9.
Third, make the denominators the same as the least common denominator (LCD). Your problem should look like:
(1x3)/(3x3) +
(1)/(9).
Fourth, simplify to get the denominators the same. Your problem should look like:
(3)/(9) +
(1)/(9).
Fifth, join the denominators. Your problem should look like:
(3+1)/(9).
Sixth, simplify. Your problem should look like:
(4)/(9), which is the answer.
