Fraction Operations Guide
Addition (+)
Find common denominator, add numerators. Example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6
Subtraction (-)
Find common denominator, subtract numerators. Example: 3/4 - 1/2 = 3/4 - 2/4 = 1/4
Multiplication (×)
Multiply numerators, multiply denominators. Example: 2/3 × 4/5 = 8/15
Division (÷)
Multiply by reciprocal. Example: 2/3 ÷ 4/5 = 2/3 × 5/4 = 10/12 = 5/6
How to Simplify Fractions (Step-by-Step)
Simplifying a fraction means reducing it to its lowest terms. Find the biggest number that divides evenly into both numerator and denominator.
Example: Simplify 8/12
- Find factors of 8: 1,2,4,8
- Find factors of 12: 1,2,3,4,6,12
- Largest common factor (GCD): 4
- Divide numerator and denominator by 4: 8÷4=2, 12÷4=3
- Simplified fraction: 2/3
Mixed Numbers & Improper Fractions Guide
Improper to Mixed Number
Divide numerator by denominator. Quotient is whole number, remainder is new numerator. Example: 7/3 = 2 remainder 1 = 2 1/3
Mixed to Improper Fraction
(Whole × Denominator) + Numerator / Denominator. Example: 2 1/3 = (2×3+1)/3 = 7/3
