The opposite is what adds up to $0$
The reciprocal is what multiplies to $1$

#### Explanation:

Opposite : reverse the sign, because $x$ added to $- x$ always adds up to $0$

Reciprocal : make the denominator and numerator change places, because $\frac{x}{y} \cdot \frac{y}{x}$ multiplies to $1$

In your case they are $4 / 2 \mathmr{and} - 2 / 4$ respectively.
(You might have written the original number as $- 2$
The answers would then have been $2 \mathmr{and} - 1 / 2$)
