a)
[tex] \frac{8}{ 3} - \frac{29}{7} = \frac{56}{21} - \frac{87}{21} = - \frac{31}{21} = - 1 \frac{10}{21} [/tex]
b)
[tex] - \frac{65}{9} + \frac{17}{3} = - \frac{65}{9} + \frac{51}{9} = - 1 \frac{5}{9} [/tex]
c)
[tex] - \frac{24}{7} - \frac{56}{8} = - \frac{192}{56} - \frac{385}{56} = - 10 \frac{17}{56} [/tex]
d)
[tex] \frac{53}{5} - \frac{159}{7} = \frac{371}{35} - \frac{795}{35} = - 12 \frac{4}{35} [/tex]
e)
[tex] - \frac{36}{7} - \frac{17}{7} = - \frac{53}{7} = - 7 \frac{4}{7} [/tex]
f)
[tex] - \frac{25}{4} + \frac{27}{8} = - \frac{50}{8} + \frac{27}{8} = - \frac{23}{8} = - 2 \frac{7}{8} [/tex]
g)
[tex] - \frac{47}{6} + \frac{91}{9} = - \frac{141}{18} + \frac{182}{18} = 2 \frac{5}{18} [/tex]
