Answer 1

Answer:

-8/5

Step-by-step explanation:

16/25 divided by -2/5

16/25 x -5/2 = -80/50 = -8/5

Answer 2

Let the other no. be x

$x \times \frac{ - 2}{5} = \frac{16}{25}$

$x = \frac{16}{25} \div \frac{ - 2}{5}$

$x = \frac{16}{25} \times \frac{ 5}{ - 2} = \frac{16}{25} \times \frac{ - 5}{2}$

$x = \frac{ - 8}{5}$
