Introduction

In mathematics, a reciprocal of a number is defined as 1 divided by that number. When dealing with fractions, finding the reciprocal involves flipping the numerator and denominator. In this article, we will explore the concept of reciprocal of a fraction and apply it to the given problem: What is the reciprocal of $$6 / 5$$?

Understanding Reciprocal of a Fraction

To find the reciprocal of a fraction, we need to flip the numerator and denominator. This means that if we have a fraction $$a / b$$, the reciprocal will be $$b / a$$. For example, the reciprocal of $$2 / 3$$ is $$3 / 2$$.

Applying the Concept to the Given Problem

Now, let's apply this concept to the given problem: What is the reciprocal of $$6 / 5$$? To find the reciprocal, we need to flip the numerator and denominator. Therefore, the reciprocal of $$6 / 5$$ is $$5 / 6$$.

Analyzing the Options

Let's analyze the options given:

A. $$12 / 10$$: This is not the reciprocal of $$6 / 5$$.
B. 1: This is not the reciprocal of $$6 / 5$$.
C. $$5 / 6$$: This is the correct reciprocal of $$6 / 5$$.
D. $$1^{1 / 5}$$: This is not the reciprocal of $$6 / 5$$.

Conclusion

In conclusion, the reciprocal of $$6 / 5$$ is $$5 / 6$$. This is because to find the reciprocal of a fraction, we need to flip the numerator and denominator. Therefore, the correct answer is option C.
