Hint: Here, we will rewrite the given number in the form of a fraction and then we will write the numerator 15 in denominator and denominator 1 in numerator to find the reciprocal of the number to find the required value.

$\Rightarrow \dfrac{{15}}{1}$
$\Rightarrow \dfrac{1}{{15}}$
Thus, the reciprocal of 15 is $\dfrac{1}{{15}}$.
Note: In this question, students should know that a square root of a number is a value that, when multiplied by itself, gives the number. We know that a rational number is a number that can expressed as the quotient or fraction of two integers, that is, $\dfrac{p}{q}$ where $p$ and $q$ are integers and $q$ is not equal to zero. We need to know that the rational numbers are closed under addition, multiplication and division, but not closed under subtraction.
