Class 6 Maths Chapter 7 Fractions Revision Notes

Quick revision notes for Class 6 Maths Chapter 7, “Fractions” — key definitions and rules at a glance for fast last-minute review. These Class 6 Mathematics Chapter 7 notes are ideal for quick revision just before exams.

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.
