respuesta porfavor​

Answer 1

Respuesta:

1)   $\frac{97}{20}$

2)   $\frac{1}{6}$

Explicación paso a paso:

1)

       $(\frac{3}{5} +\frac{5}{2})+(\frac{5}{4} +\frac{1}{2})\\\\\frac{(2*3)+(5*5)}{10}+\frac{(5*1)+(2*1)}{4}\\\\\frac{6+25}{10}+\frac{5+2}{4}\\\\\frac{31}{10}+\frac{7}{4}\\\\\frac{62+35}{20}\\\\\frac{97}{20}$

2)

       $(\frac{5}{4} +\frac{2}{3})-( \frac{1}{2}\div \frac{2}{7})\\\\(\frac{(5*3)+(4*2)}{12})-( \frac{1}{2}* \frac{7}{2})\\\\(\frac{15+8}{12})-(\frac{1*7}{2*2})\\\\\frac{23}{12}- \frac{7}{4}\\\\\frac{23-21}{12}\\\\\frac{2}{12}\\\\\frac{1}{6}$
