[tex]a) = \frac{4}{6} + \frac{3}{6} = \frac{7}{6} \times \frac{2}{15} = \frac{7}{45} \\ b) = \frac{9}{2} \times \frac{13}{12} = \frac{39}{8} = 4 \frac{7}{8} \\ c) = \frac{5}{6} \times \frac{12}{5} = 2 \\ [/tex]
[tex]d) = \frac{16}{7} \times \frac{7}{1} = 16 - ( \frac{7}{2} \times \frac{7}{2} )= \\ 16 - 24.5 = - 8.5[/tex]
