$- \frac{4 \times 3 \times 5}{5 \times 8 \times 12} = - \frac{1}{8} = - 0.125 \\ \frac{9 \times 5 \times 2}{10 \times 6 \times 3} = \frac{1}{2} = 0.5 \\ - \frac{7 \times 5 \times 24}{8 \times 6 \times 25} = - \frac{7}{2} = - 3 \frac{1}{2} = - 3.5 \\ \frac{25 \times 63 \times 22 \times 16}{44 \times 100 \times 45 \times 7} = \frac{4}{10} = 0.4$
