Mar 26, 2018

$- 9$ is the opposite
$\frac{1}{9}$ is the reciprocal

#### Explanation:

The opposite of a positive number is to add a negative sign. (Note: if the number is negative, you will change it to a positive number).

$\text{the opposite of 9 is -9}$

The reciprocal is simply flipping the denominator and numerator of a fraction. $9$ is the same as saying:

$\frac{9}{1}$ because any number divided by $1$ is itself.

So we will flip:

$\frac{9}{1} \implies \frac{1}{9}$ is the reciprocal.
