Answer 1

Hola...!

$\frac{3}{7} + \frac{1}{7} + \frac{3}{7}$                  

$\frac{4}{7} + \frac{3}{7}$                        

$\frac{7}{7} = 1 entero$

------------------------------

$\frac{10}{14} - \frac{4}{14}$

$\frac{6}{14}$

$simplificando:$

$\frac{3}{7}$

-------------------------------

$\frac{10}{15} + \frac{16}{15} + \frac{8}{15}$

$\frac{26}{15} + \frac{8}{15}$

$\frac{34}{15}$

-------------------------------

$\frac{13}{9} + \frac{5}{9}$

$\frac{18}{9}$

$simplificando:$

$2$

----------------------------------

$\frac{1}{12} + \frac{3}{12} + \frac{4}{12}$

$\frac{4}{12} + \frac{4}{12}$

$\frac{8}{12}$

$simplificando :$

$\frac{2}{2}$
