Explicação passo-a-passo:

$\begin{array}{l}\begin{array}{rr|l}\sf3&\sf15&\sf3\\\sf1&\sf5&\sf5\\\sf1&\sf1&\!\!\!\overline{~\:\sf3\cdot5=15~}\end{array}\\\\\sf MMC(3,15)=15\\\\\sf \dfrac{2}{3}+\dfrac{3}{15}=\dfrac{(15\div3)\cdot2}{15}+\dfrac{(15\div15)\cdot3}{15}\\\\\sf\dfrac{2}{3}+\dfrac{3}{15}=\dfrac{ 10}{15}+\dfrac{ 3}{15}\\\\\boxed{\boxed{\sf\dfrac{2}{3}+\dfrac{3}{15}=\dfrac{13}{15}}}\end{array}$
