[tex]1) \frac{4}{15} \\ 2) \frac{5}{12} \\ 3) = \frac{3 \times 4}{15} - \frac{5 \times 2}{15} = \frac{2}{15} \\ 4) = \frac{5 \times 4}{24} - \frac{6 \times 1}{24} = \frac{14}{24} \\ 5) = \frac{5 \times 5}{30} - \frac{6 \times 2}{30} = \frac{13}{30} \\ 6) = \frac{2 \times 4}{14} - \frac{3 \times 1}{14} = \frac{5}{14} \\ 7) = \frac{5 \times 5}{35} - \frac{7 \times 2}{35} = \frac{11}{35} \\ 8) = \frac{7 \times 3}{24} - \frac{8 \times 2}{24} = \frac{5}{24} [/tex]
