Please help, it's very urgent

Vinil7 [7]

Step-by-step explanation:

Divide by any number except 0 means the same as multiply by its inverse.

The inverse of $a$ is $\dfrac{1}{a}$

Therefore

$n\div(-1)=n\div\left(\dfrac{-1}{1}\right)=n\times\left(\dfrac{1}{-1}\right)=n\times(-1)=(-1)\times n=-1\times n$

Used the commutative property of multiplication: a × b = b × a

$\huge\boxed{-1\times n=n\div(-1)}$
