  2. Divide both the numerator and denominator by the GCD.
  3. If the fraction cannot be simplified further, convert it to a mixed number.

Formula Used

Simplified Fraction = (Numerator ÷ GCD) / (Denominator ÷ GCD)

Step-by-Step Solution

  1. Find the GCD of 15 and 4:
    • Factors of 15: 1, 3, 5, 15
    • Factors of 4: 1, 2, 4
    • Common factors: 1
