Answer✍

a. $=>\frac{2}{7} + \frac{4}{9} = (\frac{2}{7}  * \frac{9}{9}) + (\frac{4}{9}  * \frac{7}{7})  \\\\ => \frac{18}{63}  + \frac{28}{63} =\frac{18+28}{63} \\\\ => \huge\bold 46/63$

b. $=> \frac{7}{8} - \frac{3}{5} = (\frac{7}{8}  * \frac{5}{5}) - (\frac{3}{5}  * \frac{8}{8})  \\\\ => \frac{35}{40}  - \frac{24}{40} = \frac{35-24}{40} \\\\ => \huge\bold 11/40$

Hope this helps you!
