Answer :
To add the fractions 3/5 and 1/5, you simply add the numerators to get 4/5, since the denominators are the same. The correct answer is D. 4/5.
The question asks us to perform arithmetic with fractions; specifically, to find the sum of 3/5 and 1/5. To solve this problem, we simply need to add the numerators (the top numbers of the fractions) because the denominators (the bottom numbers) are already the same. We have:
3/5 + 1/5 = (3 + 1) / 5 = 4/5
So, the answer is 4/5 which corresponds to option D. The process of adding fractions is straightforward when the denominators are identical, allowing for direct addition of the numerators. Remembering that the overall denominator remains the same is crucial. No further reduction is necessary because 4/5 is already in its simplest form.
