Answer:13/12Step-by-step explanation:To find the sum of 9/12 + 4/12, we can add the numerators since the denominators are the same:9/12 + 4/12 = (9 + 4)/12 = 13/12.The fraction 13/12 is improper, but since the question asks for the sum without specifying a need to simplify or convert, we can leave it as is.
