Best Answer

When adding two fractions, you want to make sure they have the same (common) denominator. You can use any common denominator, but it's best to use the lowest (least) one so you won't have to reduce it later. Add 1/2 and 1/3. The lowest number that 2 and 3 can both go into evenly is 6, so in this case 6 is the least common denominator.
