# Do you need to get the LCM of mixed numbers?

Only to add, subtract, or compare two fractions. Note: Technically, to add two fractions (for example) you don't need the LEAST common multiple; any common multiple will do. As an example, if you want to add 1/4 + 1/6 (or any mixed number that ends with this fraction), you can use 24 as a common denominator (you can obtain this by multiplying 4 x 6), even though the least common multiple is 12.To add two mixed fractions, the easiest way is usually to add the whole part and the fractional part separately.

The LCM refers to integers. You might need to get the LCD, the least common denominator, if you want to add and/or subtract mixed numbers.

Yes, but you need to make them top-heavy fractions.
