Class 6 Maths – Chapter: Fractions
1. Introduction
- A fraction represents a part of a whole.
- Form:denominatornumerator
- Numerator: Number of parts considered
- Denominator: Total equal parts of the whole
Example:
- 43 → 3 parts out of 4
2. Types of Fractions
- Proper fraction: Numerator < Denominator (e.g., 3/5)
- Improper fraction: Numerator ≥ Denominator (e.g., 7/4)
- Mixed fraction: Whole number + Proper fraction (e.g., 2 1/3)
- Equivalent fractions: Fractions that are equal (e.g., 1/2 = 2/4)
3. Basic Operations with Fractions
a) Addition
- Same denominator: Add numerators
52+51=53 - Different denominators: Find LCM first
21+31=63+62=65
b) Subtraction
- Same denominator: Subtract numerators
- Different denominators: Find LCM
c) Multiplication
- Multiply numerators and denominators
32×43=126=21
d) Division
- Multiply by reciprocal
32÷54=32×45=1210=65
4. Conversion
- Improper fraction → Mixed fraction
Divide numerator by denominator → quotient = whole number, remainder = numerator - Mixed fraction → Improper fraction
Whole number × denominator + numerator
5. Examples
- Add fractions:
72+73=75 - Subtract fractions:
65−21=65−63=62=31 - Multiply fractions:
43×52=206=103 - Divide fractions:
87÷41=87×14=828=3½
