Question

How do you find the reciprocal of \[\dfrac{1}{2}\]?

Answer 1

Hint: For finding the reciprocal of any number you have to put that number into the denominator of one. Suppose you have number n and you want to find reciprocal of that then you have to put n into the denominator of one. So reciprocal of n is $\dfrac{1}{n}$.

Complete step by step answer:
So, as discussed in the hint, for finding the reciprocal of any number you just have to put that number into the denominator of one.
Suppose you want to find the reciprocal of number n then you have to put n into the denominator of one. So after that, you get the reciprocal of n is $\dfrac{1}{n}$.
Here, in this question number n is \[\dfrac{1}{2}\].
So, for calculating the reciprocal of \[\dfrac{1}{2}\] we will put \[\dfrac{1}{2}\] into a denominator of one.
So, we get,
$ \Rightarrow \dfrac{1}{{\dfrac{1}{2}}}$
After simplifying we get,
$ \Rightarrow 2$

So, the reciprocal of \[\dfrac{1}{2}\] is $2$

Note:
These types of questions are very easy to solve and for solving such types of questions you just need to understand one word. What does the reciprocal mean? Here, whenever you have to find a reciprocal you just have to put that number into the denominator of one.
