Multiply 3*4 = 12
The least common denominator of fractions is the smallest multiple of the denominators that they both share. To find the least common denominator of 2/3 and 7/12, you need to find the least common multiple of 3 and 12, which is 12. Therefore, the least common denominator of 2/3 and 7/12 is 12.
To solve for the answer of 2/3 + 5/12 , a good place to start would be to convert to a common denominator. To get 2/3 to have a denominator of 12, all you need to do is multiply 2/3 by 4/4 to get 8/12. Once you have a common denominator, you can just add the numerators and then simplify. 2/3 + 5/12 = (2*4)/(3*4) + 5/12 = 8/12 + 5/12 = (8+5)/12 = 13/12 = 1.0833
