Simplifying Fractions

Fractions are simplified by dividing both numerator and denominator by their greatest common divisor (GCD). For example: 6/8 → divide both by 2 → 3/4

Mixed Numbers

A mixed number combines a whole number and a fraction (e.g., 2 1/2). To convert:

Mixed to Improper: (whole × denominator) + numerator, keep denominator. 2 1/2 = (2×2+1)/2 = 5/2
Improper to Mixed: Divide numerator by denominator. 5/2 = 2 remainder 1 = 2 1/2
