Respuesta:

Procedimiento :

$\frac{3}{8} + \frac{1}{5} = \frac{3 \times 5 + 1 \times 8}{8 \times 5} = \frac{15 + 8}{40} = \frac{23}{40} \\\\ \frac{7}{2} + \frac{3}{4} = \frac{7 \times 4 + 3 \times 2}{2 \times 4} = \frac{28 + 6}{8} = \frac{34}{8} \\\\ \frac{7}{2} + \frac{9}{6} = \frac{7 \times 6 + 9 \times 2}{2 \times 6} = \frac{42 + 18}{12} = \frac{60}{12}\\\\ \frac{4}{3} + \frac{6}{4} = \frac{4 \times 4 + 6 \times 3}{3 \times 4} = \frac{16 + 18}{12} = \frac{34}{12}$

Espero que te allá ayudado .
