Respuesta:

$7) \frac{14}{3} - \frac{3}{6} = \frac{28}{6} - \frac{3}{6} = \frac{25}{6}$

$8) \frac{120}{5} - \frac{15}{6} = \frac{720}{30} - \frac{75}{30} = \frac{645}{30} = \frac{43}{2}$

$9 )\frac{30}{10} - \frac{2}{15} = \frac{90}{30} - \frac{4}{30} = \frac{86}{30} = \frac{43}{15}$

$10) \frac{21}{7} - \frac{100}{3} = \frac{63}{21} - \frac{700}{21} = - \frac{637}{21} = - \frac{91}{ 3}$

$11) \frac{8}{9} - \frac{7}{3} = \frac{8}{9} - \frac{21}{9} = - \frac{13}{9}$

$12) \frac{3}{120} - \frac{80}{5} - \frac{3}{5} = \frac{1}{40} - \frac{80}{5} - \frac{3}{5} = \frac{1}{40} - \frac{640}{40} - \frac{24}{40} = - \frac{663}{40}$

$13) \frac{120}{5} - \frac{1}{2} + \frac{15}{6} = \frac{720}{30} - \frac{15}{30} + \frac{75}{30} = \frac{780}{30} = 26$

$14) \frac{120}{5} + \frac{8}{9} - \frac{15}{6} = 24 + \frac{8}{9} - \frac{5}{2} = \frac{432}{18} + \frac{16}{18} - \frac{45}{18} = \frac{403}{18}$

$15) \frac{1}{7} - \frac{2}{5} - ( - \frac{25}{3} ) = \frac{1}{7} - \frac{2}{5} + \frac{25}{3} = \frac{15}{105} - \frac{42}{105} + \frac{875}{105} = \frac{848}{105}$
