Answer 1

Step-by-step explanation:

$9. \: \: \: \: ( - 3) \times ( \frac{2}{ - 14}) \times ( \frac{ - 5}{12}) \times ( \frac{7}{15})$

$( - 3) \times ( \frac{1}{ - 7}) \times ( \frac{ - 5}{12}) \times ( \frac{7}{15})$

$( \frac{ - 3}{ - 7}) \times \frac{ - 5}{12}) \times ( \frac{7}{15})$

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

$\frac{ - 1}{12}$

$10. \: \: \: \: let \: the \: number \: be \: x$

$according \: to \: the \: question$

$x \times \frac{11}{5} = \frac{ - 33}{25}$

$x = \frac{ - 33 \times 5}{25 \times 11}$

$x = \frac{ - 3}{5}$
