3/5 + 2 4/5 =

To solve this problem, we first convert the mixed number to an improper fraction:

\( 2 \frac{4}{5} = \frac{(2 \times 5) + 4}{5} = \frac{10 + 4}{5} = \frac{14}{5} \)

Now, we add the fractions:

\( \frac{3}{5} + \frac{14}{5} = \frac{3 + 14}{5} = \frac{17}{5} \)

We can convert this improper fraction back to a mixed number:

\( \frac{17}{5} = 3 \frac{2}{5} \)
