Find the least common denominator of 2 and 3, which is 6. Because you had to multiply 2 by 3 to get 6, you have to multiply 1 by 3, you then get 3/6. Because you had to multiply 3 by 2 to get 6, you have to multiply 1 by 2, you then get 2/6. Now, you can subtract 3/6 - 2/6, which equals 1/6. Hope this helps!
