Question

Find the multiplicative inverse or reciprocal of each of the following:
$-16$

Answer 1

Multiplicative inverse of a number is a number which when multiplied by given number yields in a result of $1$.

So, for real numbers except $0$,

Multiplicative inverse or reciprocal of a number $x$ is given by$\frac{1}{x}$, because $x\times \frac{1}{x}=1$

$\therefore$ Reciprocal of $-16$ is $\frac{1}{-16}$, which can also be written as $\frac{-1}{16}$
