Sum of $$ \dfrac{4}{17} $$ and $$ \dfrac{15}{17} $$is.
Correct option is A. $$ \dfrac{19}{17} $$
As denominators of the given fractions are same, so sum is just adding their numerators and keeping the denominator same.
$$\therefore $$ Sum of $$\dfrac{4}{17}$$ and $$\dfrac{15}{17} = \dfrac{4}{17} + \dfrac{15}{17}$$
$$ = \dfrac{4+15}{17}$$
$$ = \dfrac{19}{17}$$
$$\therefore \textbf{Option A is correct.}$$
