Class 6 Maths - CBSE
Fractions
The chapter Fractions in Class 6 CBSE Mathematics introduces students to numbers representing a part of a whole. Students learn about the numerator and denominator, proper, improper, and mixed fractions, and how to represent them on a number line. The chapter covers equivalent fractions, comparing fractions, and the crucial operations of addition and subtraction of like and unlike fractions. This foundational chapter carries significant weight in board exams, typically contributing 6 to 8 marks in term assessments. Mastering fractions is essential because they form the basis for advanced mathematical topics like ratios, decimals, percentages, and algebra in higher classes.

What is a Fraction
A fraction represents a part of a whole, written in the form a/b where 'a' is the numerator and 'b' is the denominator.
Types of Fractions
Fractions are classified into proper fractions (numerator less than denominator), improper fractions (numerator greater than or equal to denominator), and mixed fractions (combination of a whole number and a proper fraction).
Equivalent Fractions
Equivalent fractions are fractions that represent the same value or proportion of a whole, obtained by multiplying or dividing both the numerator and denominator by the same non-zero number.
Like and Unlike Fractions
Like fractions have the same denominators, making them easy to add or subtract, while unlike fractions have different denominators and require finding a common denominator first.
Comparison of Fractions
To compare fractions with different denominators, we first convert them into equivalent fractions with like denominators before checking which numerator is larger.

Board Exam Info
In CBSE Class 6 Mathematics exams, this chapter typically carries about 6 to 8 marks. Common question types include converting mixed fractions to improper fractions, finding equivalent fractions, comparing two or more fractions, and word problems based on addition and subtraction of unlike fractions.
Frequently Asked Questions
How do I add fractions with different denominators?
First, find the LCM of the denominators to make them like fractions, then add the numerators while keeping the denominator the same.
What is the difference between a proper and an improper fraction?
In a proper fraction, the numerator is smaller than the denominator (value less than 1). In an improper fraction, the numerator is greater than or equal to the denominator (value 1 or more).
How do I know if two fractions are equivalent?
Cross-multiply them; if the products are equal, the fractions are equivalent. Alternatively, reduce both fractions to their simplest form to see if they match.
