Answer

Explanation:

Step1: Encontrar el denominador común

El denominador común de 5 y 7 es (5\times7 = 35). Convertir (\frac{2}{5}) a (\frac{2\times7}{5\times7}=\frac{14}{35}) y (\frac{3}{7}) a (\frac{3\times5}{7\times5}=\frac{15}{35}).

Step2: Sumar las fracciones

(\frac{14}{35}+\frac{15}{35}=\frac{14 + 15}{35}=\frac{29}{35})

Answer:

C. (\frac{29}{35})
