Answer 2

$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\sf \bf \dfrac {1}{60}-\dfrac {1}{42}+\dfrac {1}{90}$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf \implies \dfrac {1}{60}-\dfrac {1}{42}+\dfrac {1}{90}$

$\tt {By\: taking\: LCM}$

$\sf \bf \implies \dfrac {21-30+14}{1260}$

$\sf \bf \implies \dfrac {35-30}{1260}$

$\sf \bf \implies \dfrac {5}{1260}$

$\implies {\boxed {\color{red} {\sf \bf \dfrac {5}{252}}}}$
