Respuesta:

$a)\frac{2}{3} +\frac{4}{5} =\frac{10+12}{15} =\frac{22}{15} \\\\\\ b)\frac{7}{9} +\frac{4}{3}=\frac{7+12}{9} =\frac{19}{9} \\\\\\c)3+\frac{1}{12} +\frac{2}{25} =\frac{900+25+24}{300} =\frac{949}{300} \\\\\\d)\frac{9}{10} -\frac{4}{11} =\frac{99-40}{110} =\frac{59}{110} \\\\\\e)9-\frac{1}{4} =\frac{36-1}{4} =\frac{35}{4} \\\\\\f)\frac{5}{4} -\frac{5}{12} =\frac{15-5}{12} =\frac{10}{12} =\frac{5}{6}$
