Adding Fractions with Unlike Denominators
Grade 5 · Math · Fraction Operations · Yukon, Canada
Lesson Summary
Learn how to add fractions that have different bottom numbers by finding a common denominator.
Explanation
When two fractions have different denominators, you cannot just add the top numbers together. You first need to find a common denominator, which is a number that both denominators divide into evenly. Once both fractions share the same denominator, you add the numerators and keep that denominator. Always simplify your answer if you can.
