Answer
$\dfrac{7}{13}$
Work Step by Step
Simplify the numerator and the denominator to have;
$=\dfrac{\frac{5}{5} + \frac{2}{5}}{\frac{10}{5} + \frac{3}{5}}
\\=\dfrac{\frac{7}{5}}{\frac{13}{5}}$
RECALL:
$\dfrac{\frac{a}{b}}{\frac{c}{d}}=\dfrac{a}{b} \cdot \dfrac{d}{c}$
Use the rule above to have:
$\\=\dfrac{7}{5} \cdot \dfrac{5}{13}$
Cancel the common factors to have:
$\require{cancel}
\\=\dfrac{7}{\cancel{5}} \cdot \dfrac{\cancel{5}}{13}
\\=\dfrac{7}{13}$
