1)

$( - \frac{3}{7} \times \frac{1}{4}) \times ( - 4) = - \frac{3}{28} \times ( - 4) = \frac{3}{7}$

2)

$( - 4 \frac{1}{5} \times 1.3) \times \frac{10}{13} = - \frac{21}{5} \times \frac{13}{10} \times \frac{10}{13 } = - \frac{21}{5} = - 4 \frac{1}{5} = - 4.2$

3)

$( - 5 \frac{6}{7} \times \frac{3}{13} ) \times ( - 4 \frac{1}{3}) = \frac{41}{7} \times \frac{3}{13} \times \frac{13}{3} = \frac{41}{7} = 5 \frac{6}{7}$

4) - 7 5/12
