The problem requires adding two fractions with the same denominator: \( \frac{4}{7} + \frac{2}{7} \). When denominators are identical, add the numerators and keep the denominator: \( \frac{4+2}{7} = \frac{6}{7} \).

- **A** (\( \frac{6}{14} \)) incorrectly adds denominators, which is invalid.
- **B** (\( \frac{8}{49} \)) multiplies numerators and denominators, confusing addition with multiplication.
- **C** (\( \frac{14}{28} \)) simplifies to \( \frac{1}{2} \), unrelated to the correct sum.
- **D** (\( \frac{6}{7} \)) matches the correct calculation.

minimax To find the sum of two fractions with the same denominator, you simply add the numerators together and keep the denominator the same. So, for 4/7 + 2/7, you add the numerators 4 and 2 to get 6, and the denominator remains 7.

Therefore, the correct answer is:

D. 6 over 7

Explanation:
To add fractions with the same denominator, we simply add the numerators and keep the denominator the same.
So, 4/7 + 2/7 = (4 + 2) / 7 = 6/7.

zhipu To solve the problem \( \frac{4}{7} + \frac{2}{7} \), you simply add the numerators because the denominators are the same.

\[
\frac{4}{7} + \frac{2}{7} = \frac{4 + 2}{7} = \frac{6}{7}
\]

So, the correct answer is:

D. 6 over 7

deepseekv3 To solve \( \frac{4}{7} + \frac{2}{7} \), since the denominators are the same, you simply add the numerators:

\[
\frac{4}{7} + \frac{2}{7} = \frac{4 + 2}{7} = \frac{6}{7}
\]

The correct answer is:
**D. 6 over 7**
