Answer
$\dfrac{61}{91}$
Work Step by Step
The fractions are not similar since they have different denominators. Make them similar fractions using their LCD (least common denominator).
The denominators are both prime numbers therefore their LCD is their product, which is 91.
Convert each fraction using the LCD as denominator to have:
$=\dfrac{5(7)}{13(7)}+\dfrac{2(13)}{7(13)}
\\\\=\dfrac{35}{91}+\dfrac{26}{91}
\\\\=\dfrac{61}{91}$
