Question

Can anyone give me a step by step answer for the question​

Answer 1

Answer:

It should be Multiplied by 0.8

Step-by-step explanation:

Let the number be 'x'.

According to the Question,

${( - 8)}^{ - 1} \times x = {( - 10)}^{ - 1}$

$x = \frac{ { - 10}^{ - 1} }{ { - 8}^{ - 1} }$

$x = \frac{8}{10}$

$x = 0.8$

Therefore, the Required number is 0.8
