Answer
$\dfrac{13}{36}$
Work Step by Step
Find the LCD of the two fractions:
$18 = 6(3)
\\12=6(2)$
Thus, the LCD is $6(3)(2) = 36$
Make the fractions similar using their LCD to obtain:
$=\dfrac{5(2)}{18(2)} + \dfrac{1(3)}{12(3)}
\\=\dfrac{10}{36}+\dfrac{3}{36}
\\=\dfrac{10+3}{36}
\\=\dfrac{13}{36}$
