Answer
$\dfrac{46}{45}$
Work Step by Step
Find the LCD of the two fractions:
$15 = 5(3)
\\9=3(3)$
The LCM is $5(3)(3) =45$
Thus, the LCD is also $45$
Make the fractions similar using their LCD to obtain:
$=\dfrac{2(3)}{15(3)} + \dfrac{8(5)}{9(5)}
\\=\dfrac{6}{45}+\dfrac{40}{45}
\\=\dfrac{6+40}{45}
\\=\dfrac{46}{45}$
