Question

Name the reciprocal of the following number.

$-5\frac{1}{3}$

Short answer

The reciprocal of $-5\frac{1}{3}$is localid="1645090159437" $-\frac{3}{16}$.

Step-by-step solution

Step 1. Formula Used.

The rule for converting a mixed number into an improper fraction.

$a\frac{b}{c}=\frac{\left(a\times c\right)+b}{c}$

Step 2. Definition of reciprocal.

The product of any number and its reciprocal is 1.

Step 3. Example.

Let a be any number then its reciprocal is given by

$a·\frac{1}{a}=1$

Hence, reciprocal of a is $\frac{1}{a}$.

Step 4. Find the reciprocal of the given number.

First, simplify mixed number to an improper fraction and then divide 1 by the improper fraction and simplify further as follows:

$-5\frac{1}{3}=-\frac{\left(5\times 3\right)+1}{3}=-\frac{16}{3}$

So, the reciprocal is given by

$\frac{1}{\left(-\frac{16}{3}\right)}=-\frac{3}{16}$

The reciprocal of $-5\frac{1}{3}$is localid="1645090258862" $-\frac{3}{16}$.
