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.

You can then rewrite both fractions with this common denominator, which will allow you to add the numerators together. In the example given, 5/6 and 1/4 are rewritten as 10/12 and 3/12, respectively, resulting in a sum of 13/12. video https://cdn.kastatic.org/googleusercontent/ZCdwTudJg6e6n-P2gsaUborP4izvMsGo71pvEVlX9dNYWcLXcP7VHkWpn2grt4TUP1KoJLQP9NswyHBuBLSFTBw Visually adding fractions: 5/6+1/4 To add two fractions with different denominators, you need to find the least common multiple of the denominators.
