Add and Subtract Fractions (unlike denominators) with Number Line

Fractions with unlike denominators count different size parts. To add fractions like 1/2 + 1/3, start by finding a common denominator. Next express the fractions as equivalent fractions using the common denominator. Finally, add the numerators of the fractions with like denominators. To subtract fractions with unlike denominators, express the fractions as equivalent fractions with like denominators and then subtract the numerators.
