I need to find the sum of 1/6 and 1/2. I found the LCD to be 2 so I multiplied that by the numerator and got 2/2+2/2=4/2 and simplified that to 1/2. But the answers that I get to choose from are 1/3, 1/4, 2/3 and 3/4. What did I do wrong?

Your LCD is actually 6. Multiply the 1/2 by 3 to get 3/6. 3/6 plus 1/6 is 4/6 or 2/3.

1/6+1/2=1/6+3/6=4/6 or 3/2
