Answer 2

Answer:

The other number is 135/64 .

Step-by-step explanation:

Product of two rational numbers = -9/16

One rational number = -4/15

Let another rational number is x .

According to the question,

$x \times \frac{ - 4}{15} = \frac{ - 9}{16} \\ = > x = \frac{ - 9}{16} \times \frac{15}{ - 4} \\ = > x = \frac{135}{64}$
