Answer 1

${\huge{\boxed{\tt{\color {pink}{⛤Answer:- \:}}}}}$

$= > \frac{3}{4} - \frac{6}{7} \\ = > L.C.M. \: of \: 4 \: and \: 7 \: is \: 28. \\ = > \frac{21 - 24}{28} \\ = > \frac{3}{28}$

Answer 2

Answer:

Step-by-step explanation:

⇒ $\frac{3}{4} - \frac{6}{7}$

⇒ LCM of 4, and 7 is 28

⇒ $\frac{3*7}{4*7} - \frac{6*4}{7*4}$

⇒ $\frac{21}{28} - \frac{24}{28}$

⇒ $\frac{21-24}{28}$

⇒ $\frac{3}{28}$

∴ Answer is $\frac{3}{28}$.
