a)
[tex] = \frac{6}{4} = \frac{3}{2} [/tex]
b)
[tex] = \frac{4}{6} + \frac{3}{2} + \frac{11}{3} = \frac{4 + 9 + 22}{6} = \frac{25}{6} [/tex]
c)
[tex] = \frac{1}{4} + \frac{11}{5} - \frac{7}{20} = \frac{5 + 44 - 7}{20} = \frac{42}{20} = \frac{21}{10} [/tex]
d)
[tex] = \frac{1}{10} + \frac{3}{4} + \frac{32}{15} - \frac{13}{12} = \frac{6 + 15 + 128 - 65}{60} = \frac{84}{60} = \frac{7}{5} [/tex]
