solve this question quickly

Answer 1

$\textbf{ANSWER:}$

$\frac{4}{3} \times \frac{3}{8} = \frac{1}{2}$
_________

$\frac{5}{7} \div \frac{13}{5} \times\frac{5}{7} \\ \\ =》\frac{5}{7} \times \frac{5}{13} \times\frac{5}{7} \\ \\ = 》 \frac{125}{637}$
_________

Altogether:

$\frac{1}{2} + \frac{125}{637} - \frac{2}{5} \\ \\ LCM \\ \\ = > \frac{3185+1250+2548}{6370} \\ \\ = > \frac{6983}{6370}$
_________

That's the answer.
