Step-by-step explanation:

let the other rational number be x then

$\frac{5}{12} \times x = \frac{ - 3}{25} \\ = > \frac{5x}{12} = \frac{ - 3}{25} \\ = > cross \: multiply \: we \: get\\ = > 125x = - 36 \\ = > x = \frac{ - 36}{125}$

Verification :-

$\frac{5}{12} \times \frac{ - 36}{125} \\ = > \frac{ - 180}{1500} = \frac{ -3 }{25}$

so the other number is -36/125
