Question

can I get the answer of this please
I am confusing​

Answer 1

$\frac{3}{7} + \frac{4}{9} + \frac{ - 11}{7} + \frac{7}{9}$

$\implies (\frac{3}{7} - \frac{11}{7} )+ (\frac{4}{9} + \frac{7}{9} )$

$\implies \frac{3 - 11}{7} + \frac{4 + 7}{9}$

$\implies \frac{ - 8}{7} + \frac{11}{9}$

$\implies \frac{ - 72+ 77}{63}$

$\therefore \frac{5}{63}$
