Question

How do you find the reciprocal of $ \dfrac{1}{{22}} $ ?

Answer 1

Hint: Before we start solving this question, refer to the basic concepts of rational number, irrational number and its reciprocal. Reciprocal is also known as the “multiplicative inverse” which is simply one of a pair of numbers that, when multiplied together is equal to one.

Complete step-by-step answer:
A rational number is the number which can be expressed as the ratio of two numbers or which can be expressed as the p/q form or as the quotient or the fraction with non-zero denominator whereas, the numbers which are not represented as the rational are known as the irrational number.
Given number is the rational number $ \dfrac{1}{{22}} $
Reciprocal of the above expression is found by exchanging the numerator’s value in denominator and denominator’s value in numerator.
So, $ \dfrac{1}{{22}} $ the reciprocal will be $ \dfrac{{22}}{1} $
So, the correct answer is “ $ \dfrac{{22}}{1} $ ”.

Note: In mathematics, the multiplicative inverse means the reciprocal. Let us suppose that “x” be any number then its multiplicative inverse can be expressed as $ $ $ \dfrac{1}{x}{\text{ and }}{{\text{x}}^{ - 1}} $ . Always remember that the reciprocal of the positive number is always positive.
