Answer 1

The answer is A) 14/12

Explanation:

The common denominator here is 12.

1/3 is multiplied by 4 to get 12 on the bottom, and 4 on the top (4/12)

2/4 is multiplied by 3 to get 12 on the bottom, and 6 on the top (6/12)

4/12 stays the same

Now, we have 4/12 + 6/12 + 4/12

Add all the numerators to get 14/12 as your answer.
