The least common multiple (lcm) is used to find an equivalent fraction in order to add or subtract fractions. If your problem is 1/3 +1/2 you have to use the multiples to find the common denominator The multiples of 3 are 3,6,9,12,15,... The multiples of 2 are 2,4,6,8,10,... The least common multiple of those two numbers is 6 so I would say 1/3 = 2/6 and 1/2 = 3/6. Now you could add the two fractions since they have a common denominator. 2/6 + 3/6 = 5/6
