Short Answer

Expert verified

The reciprocal of the $\frac{1}{2}$ is $2$ .

Step by step solution

Step 1- Given information

We have, a number $\frac{1}{2}$ .

To find the reciprocal of the given number

Step 2- concept used

The reciprocal or multiplicative inverse of a number $x$ is the number which, when multiplied by $x$ then gives $1$ .

Such that $x \times \frac{1}{x} = 1$

Thus, $x$ is the reciprocal of $\frac{1}{x}$ and $\frac{1}{x}$ is the reciprocal of $x$ .

Step 3- To find the reciprocal

Let the reciprocal of the given number $\frac{1}{2}$ is $= x .$

So,

$\begin{array}{l} \frac{1}{2} \times x = 1 \\ \Rightarrow x = 2 \end{array}$

Hence, the reciprocal of the $\frac{1}{2}$ is $2$ .
