[tex] = \frac{29}{9} - \frac{8}{9} = \frac{7}{3} [/tex]
[tex] = (5 - 3) + ( \frac{3}{4} - \frac{1}{4}) = 2 + \frac{1}{2} = 2 \frac{1}{2} [/tex]
[tex] = \frac{38}{9} - \frac{14}{9} = \frac{8}{3} [/tex]
[tex] = \frac{35}{8} - \frac{23}{8} = \frac{3}{2} [/tex]
[tex] = \frac{31}{6} - \frac{17}{6} = \frac{7}{3} [/tex]
