Class 6 Maths Chapter 7 Fractions Revision Notes

A fraction in Chapter 7 is just parts taken over parts available, but from there the chapter builds up equivalence, comparison, and addition — the core rules are recapped below.

Key Definitions

• Fraction: numerator/denominator — numerator = parts taken, denominator = total equal parts.
• Unit fraction: numerator = 1 (e.g., 1/2, 1/9); larger denominator means a smaller value.
• Proper fraction: numerator < denominator. Improper fraction: numerator ≥ denominator.
• Mixed fraction: whole number + proper fraction (e.g., 4½).
• Equivalent fractions: same value, different numerator/denominator (e.g., 1/2 = 2/4 = 4/8).
• Like fractions: same denominator. Unlike fractions: different denominators.

Key Rules

• Simplest form: divide numerator and denominator by their HCF.
• Comparing unlike fractions: convert to a common denominator (LCM), then compare numerators.
• Addition/subtraction (“Brahmagupta’s method”): like fractions — add/subtract numerators directly; unlike fractions — convert to a common denominator (LCM) first.

Scope Note

• This Class 6 chapter covers fractional units, number-line fractions, mixed fractions, equivalence, comparison, and addition/subtraction only.
• Multiplication, division, and decimal fractions are not part of this chapter — they appear in Class 7.

Frequently Asked Questions

What does a fraction represent, and what do its numerator and denominator each indicate?
A fraction represents a part of a whole, where the denominator indicates the total number of equal parts the whole is divided into, and the numerator indicates how many of those parts are being considered.

How can you compare two fractions with different denominators?
Two fractions with different denominators are compared by converting them to equivalent fractions with a common denominator, after which the fraction with the larger numerator represents the greater value.
