Answer 1

Answer:

Option B) -⅔

Step-by-step explanation:

let the number be X

B/Q,

(-8)·¹ × X = 12·¹

=> 1/·8 × X = 1/12

=> X = 1/12 × -8/1

=> X = -8/12 = -4/6 = -2/3

Hope that was helpfull

Answer 2

$\large\bold{\underline{\underline{Given:-}}}$

Product of two numbers = ${12}^{ (- 1)}$

One of the number = $( { - 8})^{ (- 1)}$

$\large\bold{\underline{\underline{To\:find:-}}}$

The other number.

$\large\bold{\underline{\underline{Solution:-}}}$

Let the other number be $x$.

As per the question,

Product of two numbers = ${12}^{ (- 1)}$

:⟼  ${ - 8}^{( - 1)} \times x = {12}^{( - 1)}$

:⟼  $\frac{ 1}{ - 8} \times x = \frac{1}{12}$

:⟼  $x = \frac{1}{12} \times \frac{ - 8}{1}$

:⟼  $x = \frac{ - 8}{12}$

:⟼  $x = \frac{ - 2}{3}$

Therefore, the number to be multiplied with $( { - 8})^{ (- 1)}$ to obtain ${12}^{ (- 1)}$ is $\boxed{ \frac{ - 2}{3} }$.

$\bigstar \: \boxed{\sf{\color{red}{ (B) \:\frac{ - 2}{3} }}}$ ✔

Note:

${a}^{( - m)} = \frac{1}{ {a}^{(m)} }$
