5/2+2/5

To add the fractions \( \frac{5}{2} \) and \( \frac{2}{5} \), you'll need a common denominator.

The least common multiple of 2 and 5 is 10.

Now, convert each fraction:

\[ \frac{5}{2} = \frac{5 \times 5}{2 \times 5} = \frac{25}{10} \]

\[ \frac{2}{5} = \frac{2 \times 2}{5 \times 2} = \frac{4}{10} \]

Now, add the two fractions:

\[ \frac{25}{10} + \frac{4}{10} = \frac{25 + 4}{10} = \frac{29}{10} \]

So, \( \frac{5}{2} + \frac{2}{5} = \frac{29}{10} \) or 2.9 in decimal form.
