Answer 2

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

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

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

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

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

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