CBSE Class 7 Maths Chapter 8 Notes: Working with Fractions

Fractions are an essential part of Mathematics and are used in measurements, sharing, comparisons, and everyday calculations. In CBSE Class 7 Maths Chapter 8, students learn how to work with fractions through different mathematical operations and practical examples. The chapter builds a strong foundation by explaining how fractions can be represented, simplified, and used in problem-solving.

Working With Fractions Class 7 Maths Notes make the chapter easier to understand by breaking down each concept into simple explanations and examples. These CBSE Class 7 Maths Chapter 8 Notes help students practice calculations step by step, understand fraction relationships clearly, and improve accuracy while solving numerical problems. 

Working With Fractions Class 7 Maths Notes

Working With Fractions Class 7 Maths Notes provide a simplified overview of all the major concepts discussed in the chapter. The notes explain how to handle different fraction operations, compare values, and solve application-based questions using easy methods. 

Fraction Definition

A fraction represents a part of a whole or a collection. It consists of two main parts.

• Numerator: The top number, indicating how many parts are considered.

• Denominator: The bottom number, indicating the total number of equal parts in the whole.

Equivalent Fractions

Equivalent fractions are different representations that hold the same value. They look different but signify the same portion of a whole. For example, 1/2, 2/4, and 3/6 are all equivalent fractions.

Addition and Subtraction of Fractions

Performing these operations depends on the denominators.

• Like Fractions: To add or subtract like fractions (those with the same denominator), combine the numerators while keeping the denominator unchanged. For example .

• Unlike Fractions: Convert them into equivalent like fractions first. Find the Least Common Multiple (LCM) of the denominators. Then, add or subtract the new numerators. 

Multiplication of Fractions

Multiplication of fractions involves straightforward steps.

• Fraction by Fraction: Multiply the numerators together and the denominators together. For example, .

• Fraction by Whole Number: Treat the whole number as a fraction with a denominator of 1. Then multiply as usual. 

• Mixed Numbers: Convert mixed numbers to improper fractions before multiplying.

• Order of Multiplication: Fractions can be multiplied in any order because the final result remains the same.

Reciprocal of a Fraction

The reciprocal of a fraction is its multiplicative inverse. You find it by simply flipping the numerator and denominator. For example, the reciprocal of ⅗ is 5/3. 

This concept is important for division of fractions, a key topic in Working with Fractions Class 7 Chapter 8 Ganita Paraksh notes. A number multiplied by its reciprocal always equals 1. 

Division of Fractions

To divide fractions, use the "Keep, Change, Flip" method.

1. Keep: Retain the first fraction as it is.

2. Change: Change the division sign (÷) to a multiplication sign (×).

3. Flip: Find the reciprocal of the second fraction.

4. Then, perform the multiplication.
