Given:

One number is (-1/8)

To find

A number that will be multiplied to (-1/8) to get 1/10

So,

Let the number be n

Now,

The equation formed according to the question is,

⇒ (-1/8) * n = 1/10

⇒ n = (1/10) ÷ (-1/8)

[by transporting (-1/8) to RHS]

⇒ n = (1/10) * (-8/1)

⇒ n = (-8/10)

[Now, (-8 ÷ 2 = -4) and (10 ÷ 2 = 5)]

⇒ n = (-4)/5

Hence,

The number is (-4/5) which should be multiplied to (-1/8) to get the product (1/10).

So,

Option second is the correct answer, (-4/5)
