Question

What should be divided by $$\dfrac{1}{2}$$ to obtain the greatest negative integer?

Answer 1

As we know that greatest negative number is $$-1$$.

Let $$y$$ be the number.

ACQ,
$$\Rightarrow \dfrac{1}{2}÷y=-1$$
$$\Rightarrow \dfrac{1}{2}\times\dfrac{1}{y}=-1$$

$$\Rightarrow y=\dfrac{-1}{2}$$

Therefore, $$\dfrac{-1}{2}$$ is the required number.
