Answer 2

$( \frac{7}{3} - \frac{4}{3} ) - \frac{12}{13}$

$= \frac{7 - 4}{3} - \frac{12}{13}$

$= \frac{3}{3} - \frac{12}{13}$

$= 1 - \frac{12}{13}$

$= \frac{13}{13} - \frac{12}{13}$

$= \frac{13 - 12}{13}$

$= \frac{1}{13}$

$( \frac{5}{6} + \frac{7}{6} ) - \frac{1}{7}$

$= \frac{5 + 7}{6} - \frac{1}{7}$

$= \frac{12}{6} - \frac{1}{7}$

$= 2 - \frac{1}{7}$

$= \frac{14}{7} - \frac{1}{7}$

$= \frac{14 - 1}{7}$

$= \frac{13}{7}$

$\frac{4}{3} - ( \frac{9}{11} + \frac{2}{11} )$

$= \frac{4}{3} - \frac{9 + 2}{11}$

$= \frac{4}{3} - \frac{11}{11}$

$= \frac{4}{3} - 1$

$= \frac{4}{3} - \frac{3}{3}$

$= \frac{4 - 3}{3}$

$= \frac{1}{3}$
