$\dfrac{5}{11}$ $× \dfrac{18}{29}$ $+ \dfrac{5}{11}$ $× \dfrac{8}{29}$ $+ \dfrac{5}{11}$ $× \dfrac{19}{29}$
$= \dfrac{5}{11}× $$(\dfrac{18}{29} +$$\dfrac{8}{29}+$$\dfrac{19}{29})$
$=\dfrac{5}{11} ×$$(\dfrac{18 + 8 + 19}{29})$
$=\dfrac{5}{11}×$$\dfrac{45}{29}$
$=\dfrac{5 × 45}{11 × 29}$
$=\dfrac{225}{319}$
