Math 2-6: Adding and Subtracting Unlike Fractions Objective: How to add and subtract fractions with unlike denominators.

Vocabulary unlike fractions – fractions with different denominators. least common denominator (LCD) – the least common multiple of the denominators.

Adding or Subtracting Unlike Fractions rewrite the fractions with a common denominator. add or subtract and simplify.

Adding or Subtracting Mixed Numbers with Unlike Fractions write the mixed numbers as improper fractions. rewrite the fractions with a common denominator. add or subtract and simplify.

Examples *add or subtract and write in simplest form*
