So, using the above formula we get,
Converse of \left(~ p ∧ q\right) ⇒ r≡ r ⇒ ( ~ p ∧ q )≡ \left(~ r\right) ∨ \left(~ p ∧ q\right)≡ \left(~ p ∧ q\right) ∨ \left(~ r\right)≡ ~ \left(p ∨ ~ q\right) ∨ \left(~ r\right)\left\{\text{as} ~ \left(A ∨ B\right) ≡ ~ A ∧ ~ B\right\}≡ \left(p ∨ \left(~ q\right)\right) ⇒ \left(~ r\right)
