3 <p>The reciprocal of a fraction means swapping numerator and denominator. It involves interchanging the numerator and denominator of a fraction. For example, the reciprocal of 5/2 is 2/5. This process of reversing a fraction is also known as multiplicative inverse.</p>

7 <p>The mathematical concept<a>of</a>reciprocal means the<a>multiplicative inverse</a>of a<a>number</a>. It is what you get when you reverse the positions of the<a>numerator</a>and the<a>denominator</a>. For example, the reciprocal of \( \frac{2}{7} \) is \( \frac{7}{2} \), \( \frac{8}{3} \) is \( \frac{3}{8} \), etc. </p>

8 <p>When a<a>fraction</a>is multiplied by the reciprocal, it always results in 1. Let us understand this by an example. Let’s say, 2, the reciprocal of 2 is ½ and then multiply 2 by its reciprocal, 2 \( \frac{1}{2} \) = 1 </p>

9 <h2>What are Fractions?</h2>

10 <p>A fraction represents a portion of a whole or the<a>ratio</a>of two<a>whole numbers</a>. It can be represented in the form \(\frac{p}{q} \), where p and q are<a>integers</a>, and q≠0. Here, \(\frac{p}{q} \) is called a fraction. It is a horizontal line that separates the two integers, called the fractional bar. The top number is called the numerator and the bottom number is called the denominator. For example, a ratio of 5:10 can be written as </p>

11 <p> \(\frac{5}{10} \) ⇒ \(\frac{p}{q} \) ⇒ \(\frac{\text{Numerator}}{\text{Denominator}} \)</p>

12 <h2>Parts of Fractions</h2>

13 <p>A fraction has two parts:</p>

14 <ul><li><strong>Numerator:</strong><a>Numerator</a>means number above the fraction line. It tells us how many parts of the whole are being considered. For instance, in a fraction 5/6, 5 is the numerator, meaning that you are working with 5 parts out of 6. </li>

15 <li><strong>Denominator:</strong>This is the number below the fraction line. It shows how many total numbers of equal parts the whole is divided into. It indicates how many pieces are there in the entire unit or<a>set</a>. For instance, in a fraction 5/6, 6 is the denominator, meaning the whole is divided into 6 equal parts. </li>
