$Let \: the \: other \: number \: be \: x$

According to question

$= > \frac{ - 15}{20} \times x = \frac{ - 5}{7}$

$= > x = \frac{ - 5}{7} \div \frac{15}{20}$

$= > x = \frac{ - 5}{7} \times \frac{20}{15}$

$= > x = \frac{ - 20}{7 \times 3}$

$= > x = \frac{ - 20}{21}$

Hence the other Number is -20/21
