Answer 1

$= \frac{11}{4} - \frac{5}{4} = \frac{3}{2}$

$= \frac{29}{9} - \frac{8}{9} = \frac{7}{3}$

$= (5 - 3) + ( \frac{3}{4} - \frac{1}{4}) = 2 + \frac{1}{2} = 2 \frac{1}{2}$

$= \frac{38}{9} - \frac{14}{9} = \frac{8}{3}$

$= \frac{35}{8} - \frac{23}{8} = \frac{3}{2}$

$= \frac{31}{6} - \frac{17}{6} = \frac{7}{3}$
