Question

I have a question?

Answer 1

About what?

Answer 2

Does that fraction equals a negative whole or just a whole ?

Answer 3

Negative whole.

Because of you multiply numerator and denominator by -1, you would get \(\dfrac{-1}{1}\).

\(\dfrac{1}{-1}~=~1\cdot\dfrac{1}{-1}~=~\dfrac{-1}{-1}\cdot\dfrac{1}{-1}~ = ~\dfrac{-1}{1}\)

Divide anything by 1 won't do anything, so \(\dfrac{-1}{1}=-1\)

So that's why \(\dfrac{1}{-1} = -1\)

Answer 4

Is this clear?
