3 <p>A unit fraction is a type of fraction where the numerator is always 1 and the denominator is a natural number. It is written in the form 1/p, where p is a natural number; for example, 1/2, 1/5, 1/9. It is used to understand how a whole object is divided into equal parts.</p>

7 <p>A<a></a><a>fraction</a>represents a part of a whole and is written as p/q, where p is the<a>numerator</a>and q is the<a>denominator</a>. When the numerator is always 1 for a fraction, and the denominator is any<a></a><a>natural number</a>, it is known as a unit fraction. It means that any fraction in the form 1/q is termed a unit fraction. Since ‘unit’ means one, a unit fraction shows one part out of the total number of equal parts. Fractions such as \(\frac{1}{4}\), \(\frac{1}{10}\), \(\frac{1}{25}\), etc., are examples of<a>unit fractions</a>. </p>

8 <p><strong>Definition of Unit Fraction</strong> </p>

9 <p>A unit fraction is a fraction in which the<a>numerator</a>is 1 and the<a>denominator</a>is any natural number<a>greater than</a>1. It represents one equal part of a whole that is divided into 'q' equal parts, and is written in the form \(\frac{1}{q}\). </p>

10 <p>Unit Fraction Example: Imagine you cut a pizza into 8 equal slices. If you take one slice, you have to take 1 out of 8 parts, which is the unit fraction ⅛. This shows how a unit fraction represents one equal part of a whole.</p>

11 <h2>Difference Between Unit and Non-Unit Fractions</h2>

12 <p>Fractions are classified as unit or non-unit fractions based on the numerator. Let’s understand the difference between unit fractions and non-unit fractions.</p>

13 <strong>Unit Fraction</strong><strong>Non-Unit Fraction</strong>The numerator of a unit fraction is always 1 The numerator of a non-unit fraction is greater than 1 A unit fraction is always a<a>proper fraction</a>A non-unit fraction can be a proper or an<a>improper fraction</a>Example: 1/2, 1/5, 1/7 Examples: 2/5, 6/7, 8/3<h2>How to Multiply Unit Fractions</h2>

14 <p>Multiplying unit fractions is the same as multiplying any fractions. We can multiply a unit fraction with a<a></a><a>whole number</a>, another unit fraction, or a non-unit fraction.</p>

15 <p><strong>Multiplying Unit Fractions with Unit Fractions</strong></p>

16 <p>When multiplying two unit fractions, multiply the<a></a><a>numerators</a>and denominators.</p>

17 <p>\(\frac{1}{a} × \frac{1}{b} = \frac{1 × 1} {a × b} = \frac{1}{ab}\).</p>

18 <p>For example, </p>

19 <p>\(\frac{1}{5} × \frac{1}{7} = \frac{1 × 1}{5 × 7}\)</p>

20 <p>\(= \frac{1}{35}\). </p>

21 <p><strong>Multiplying Unit Fractions with Non-unit Fractions</strong></p>

22 <p>To multiply a unit fraction by a non-unit fraction, multiply the numerators and denominators in the same way.</p>

23 <p>\(\frac{1}{a} × \frac{p}{q} = \frac{1 × p}{a × q} = \frac{p}{aq}\)</p>

24 <p>For example, </p>

25 <p>\(\frac{1}{4} ×\frac{3}{8} = \frac{1 × 3}{4 × 8} = \frac{3}{32}\)</p>

82 <h3>Explanation</h3>

83 <p> A unit fraction is a fraction that has 1 as a numerator.</p>

84 <p>In the first circle, the fraction is \(\frac{1}{4}\); it is a unit fraction, as the numerator is 1.</p>

85 <p>In the second circle, the fraction is \(\frac{3}{6}\), as the numerator is 3, which is not a unit fraction.</p>
