$\frac{7}{6} + \frac{2}{5} = \frac{35 + 12}{30} = \frac{47}{30}$

b)

$\frac{1}{7} + \frac{1}{8} = \frac{8 + 7}{56} = \frac{15}{56}$

c)

$\frac{7}{13} + \frac{5}{10} = \frac{70 + 65}{130} = \frac{135}{130}$

d)

$\frac{7}{5} - \frac{1}{3} = \frac{21 - 5}{15} = \frac{16}{15}$

e)

$\frac{8}{7} - \frac{9}{11} = \frac{88 - 63}{77} = \frac{25}{77}$

f)

$\frac{11}{4} - \frac{1}{9} = \frac{99 - 4}{36} = \frac{95}{36}$
