LCM of 9 and 18 = 18.
⇒7×29×2−518⇒1418−518⇒14−518⇒918⇒12\Rightarrow \dfrac{7 \times 2}{9 \times 2} - \dfrac{5}{18}\\[1em] \Rightarrow \dfrac{14}{18} - \dfrac{5}{18}\\[1em] \Rightarrow \dfrac{14 - 5}{18}\\[1em] \Rightarrow \dfrac{9}{18}\\[1em] \Rightarrow \dfrac{1}{2}⇒9×27×2−185⇒1814−185⇒1814−5⇒189⇒21
Hence, option 3 is the correct option.
