To add ( \frac{2}{3} + \frac{4}{5} ), you first need to find a common denominator, which in this case is 15. Then, you convert both fractions to have the same denominator:

( \frac{2}{3} = \frac{2 \times 5}{3 \times 5} = \frac{10}{15} )

( \frac{4}{5} = \frac{4 \times 3}{5 \times 3} = \frac{12}{15} )

Now, you can add the fractions:

( \frac{10}{15} + \frac{12}{15} = \frac{10 + 12}{15} = \frac{22}{15} )

So, ( \frac{2}{3} + \frac{4}{5} = \frac{22}{15} ).
