Answer 3

To add mixed numbers, you first add the whole numbers and then add the fractions separately. Here's how you can calculate each of the expressions:

1. $3 \frac{2}{7} + 5 \frac{5}{14}$:

   First, add the whole numbers: $3 + 5 = 8$.

   Next, add the fractions: $\frac{2}{7} + \frac{5}{14}$.

   To add these fractions, you need a common denominator, which is 14.

   $\frac{2}{7} = \frac{4}{14}$ (by multiplying the numerator and denominator of $\frac{2}{7}$ by 2).

   Now, add the fractions: $\frac{4}{14} + \frac{5}{14} = \frac{9}{14}$.

   So, $3 \frac{2}{7} + 5 \frac{5}{14} = 8 \frac{9}{14}$.

2. $6 \frac{3}{8} + 2 \frac{1}{4}$:

   First, add the whole numbers: $6 + 2 = 8$.

   Next, add the fractions: $\frac{3}{8} + \frac{1}{4}$.

   To add these fractions, you need a common denominator, which is 8.

   $\frac{3}{8} = \frac{3}{8}$ (already in the same denominator).

   Now, add the fractions: $\frac{3}{8} + \frac{1}{4} = \frac{3}{8} + \frac{2}{8} = \frac{5}{8}$.

   So, $6 \frac{3}{8} + 2 \frac{1}{4} = 8 \frac{5}{8}$.

3. $3 \frac{6}{13} + 2 \frac{9}{26}$:

   First, add the whole numbers: $3 + 2 = 5$.

   Next, add the fractions: $\frac{6}{13} + \frac{9}{26}$.

   To add these fractions, you need a common denominator, which is 26.

   $\frac{6}{13} = \frac{12}{26}$ (by multiplying the numerator and denominator of $\frac{6}{13}$ by 2).

   Now, add the fractions: $\frac{12}{26} + \frac{9}{26} = \frac{21}{26}$.

   So, $3 \frac{6}{13} + 2 \frac{9}{26} = 5 \frac{21}{26}$.

Therefore, the results are:

1. $3 \frac{2}{7} + 5 \frac{5}{14} = 8 \frac{9}{14}$
2. $6 \frac{3}{8} + 2 \frac{1}{4} = 8 \frac{5}{8}$
3. $3\frac{6}{13}+2\frac{9}{26}=5\frac{21}{26}$ 0 0
