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)
