Class 5 Maths - WEST-BENGAL
Fractions
In Class 5 Mathematics under the West Bengal Board of Secondary Education (WBBSE), the chapter on Fractions builds upon basic part-whole concepts learned earlier. Students explore types of fractions including proper, improper, mixed fractions, and equivalent fractions. The curriculum emphasizes fundamental operations such as addition and subtraction of like and unlike fractions, finding the lowest terms, and converting between mixed numbers and improper fractions. Mastery of this chapter is vital for board exams as it forms the foundational arithmetic required for decimals, percentages, and higher-level problem-solving in Class 6 and beyond.

Proper Fraction
A fraction where the numerator is smaller than the denominator, representing a value less than 1.
Improper Fraction
A fraction where the numerator is greater than or equal to the denominator, representing a value equal to or greater than 1.
Mixed Fraction
A combination of a whole number and a proper fraction, representing a value greater than 1.
Equivalent Fractions
Fractions that look different but represent the same exact part of a whole, obtained by multiplying or dividing the numerator and denominator by the same number.
Like and Unlike Fractions
Like fractions have the same denominator, making them easy to add or subtract, while unlike fractions have different denominators.

Board Exam Info
In West Bengal (WBBSE) Class 5 Mathematics evaluations, the Fractions chapter typically carries around 8 to 12 marks. Common question types include converting mixed fractions to improper fractions (and vice versa), simplifying fractions to their lowest terms, finding equivalent fractions, and solving word problems involving addition and subtraction of unlike fractions.
Frequently Asked Questions
How do I add fractions with different denominators?
First, find the Least Common Multiple (LCM) of the denominators to convert the unlike fractions into like fractions, then add their numerators while keeping the common denominator the same.
What is the difference between a proper and an improper fraction?
In a proper fraction, the top number (numerator) is smaller than the bottom number (denominator). In an improper fraction, the numerator is equal to or bigger than the denominator.
How can I reduce a fraction to its lowest terms?
Find the Highest Common Factor (HCF) of both the numerator and the denominator, and then divide both numbers by that HCF.
