More Details About Fraction Simplification
Simplifying a fraction means reducing it to its lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD).
Example Calculation

Example: Simplifying 24/36 to 2/3 by dividing both numbers by their GCD of 12.
How It Works
- Find the GCD of the numerator and denominator
- Divide both numbers by the GCD
- The resulting fraction is in its simplest form
Example Steps:
- Original fraction: 24/36
- GCD of 24 and 36 is 12
- 24 ÷ 12 = 2 (new numerator)
- 36 ÷ 12 = 3 (new denominator)
- Simplified fraction: 2/3
