To solve \( \frac{13}{14} + \frac{7}{14} \), add the numerators (13 + 7 = 20) while keeping the denominator (14) unchanged, resulting in \( \frac{20}{14} \). Simplifying \( \frac{20}{14} \) by dividing numerator and denominator by 2 gives \( \frac{10}{7} \), which is equivalent to the mixed number \( 1 \frac{3}{7} \).

13/14 + 7/14 = 20/14 = 10/7 = 1 and 3/7.

minimax To solve the question, we simply add the two fractions together:

13/14 + 7/14 = (13 + 7) / 14
= 20 / 14

Since 20/14 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2, we get:

20 / 14 = (20 ÷ 2) / (14 ÷ 2)
= 10 / 7

10/7 is an improper fraction, which can be expressed as a mixed number:

10/7 = 1 and 3/7

Therefore, the correct answer is:

B. 1 and 3 over 7

kimi To solve this, you can add the fractions since they have the same denominator:

\[ \frac{13}{14} + \frac{7}{14} = \frac{13 + 7}{14} = \frac{20}{14} \]

Now, simplify the fraction:

\[ \frac{20}{14} = \frac{10}{7} \]

This fraction cannot be simplified further, and it represents 1 whole and 3/7 of another whole. So the correct answer is:

B. 1 and 3 over 7

zhipu To solve the expression \( \frac{13}{14} + \frac{7}{14} \), we add the numerators since the denominators are the same:

\[ \frac{13 + 7}{14} = \frac{20}{14} \]

Next, we simplify \( \frac{20}{14} \):

\[ \frac{20}{14} = \frac{10}{7} \]

Since \( \frac{10}{7} \) is an improper fraction, we convert it to a mixed number:

\[ \frac{10}{7} = 1 \frac{3}{7} \]

Therefore, the correct answer is:

B. 1 and 3 over 7

deepseekv3 To solve the problem, we add the two fractions since they have the same denominator:

\[
\frac{13}{14} + \frac{7}{14} = \frac{13 + 7}{14} = \frac{20}{14}
\]

We can simplify \(\frac{20}{14}\) by dividing the numerator and denominator by 2:

\[
\frac{20 \div 2}{14 \div 2} = \frac{10}{7}
\]

The fraction \(\frac{10}{7}\) can be expressed as a mixed number:

\[
\frac{10}{7} = 1 \frac{3}{7}
\]

Thus, the correct answer is:

**B. 1 and 3 over 7**
