The least common multiple of 2 and 3 is 6, so you can rewrite the fractions as 3/6 and 2/6, respectively. This allows you to add the numerators together, resulting in a sum of 5/6. video https://cdn.kastatic.org/ka_thumbnails_cache/80245688-2e3a-41f7-bfb3-118e864362cc_1280_720_base.png Adding fractions with unlike denominators introduction To add fractions with different denominators, such as 1/2 and 1/3, you need to find a common denominator.
