Respuesta:

$\frac{4}{2}+\frac{8}{5}=\frac{4*5+2*8}{2*5}=\frac{20+16}{10}=\frac{36}{10}=\frac{18}{5}$

$\frac{5}{7}+\frac{4}{5}=\frac{5*5+7*4}{7*5}=\frac{25+28}{35}=\frac{53}{35}$

$\frac{2}{3}+\frac{5}{2}=\frac{2*2+3*5}{3*2}=\frac{4+15}{6}=\frac{19}{6}$

$\frac{6}{4}-\frac{3}{7} =\frac{6*7-(4*3)}{4*7}=\frac{42-12}{28}=\frac{30}{28}=\frac{15}{14}$

$\frac{9}{5}-\frac{7}{4}=\frac{9*4-(5*7)}{5*4}=\frac{36-35}{20}=\frac{1}{20}$
