Class 6 Maths - WEST-BENGAL
Fractions
The Fractions chapter in Class 6 West Bengal Board (WBBSE) mathematics introduces students to parts of a whole and numbers outside of integers. Students learn about proper, improper, and mixed fractions, equivalent fractions, and simplest forms. They also master fundamental arithmetic operations including addition, subtraction, multiplication, and division of fractions, along with word problems. Fractions are a foundational topic heavily featured in the WBBSE annual exams, forming the core for ratios, percentages, and advanced algebra in higher classes. Scoring well here requires precision with LCM for denominators and a clear understanding of fraction types.

Fraction
A fraction represents a part of a whole, written as numerator/denominator, where the denominator shows total equal parts and the numerator shows parts taken.
Types of Fractions
Proper fractions have a smaller numerator than denominator (less than 1), improper fractions have a larger numerator, and mixed fractions combine a whole number and a proper fraction.
Equivalent Fractions
Fractions that represent the same value or proportion, obtained by multiplying or dividing both the numerator and denominator by the same non-zero number.
Simplest Form
A fraction is in its simplest or lowest form when its numerator and denominator have no common factor other than 1.
Addition and Subtraction of Fractions
To add or subtract fractions, first convert them to like fractions by finding the LCM of their denominators, then operate on the numerators.

Frequently Asked Questions
How do we add fractions with different denominators?
First, find the LCM of the denominators to make them equal (like fractions), and then add only the numerators while keeping the denominator the same.
What is the difference between an improper fraction and a mixed fraction?
An improper fraction has a numerator greater than or equal to its denominator (e.g., 7/4), whereas a mixed fraction consists of a whole number and a proper fraction (e.g., 1 3/4).
How do we simplify a fraction to its lowest terms?
Find the HCF of both the numerator and the denominator, and then divide both numbers by that HCF until 1 is their only common factor.
