what is 4 5/6 + 3 2/3? First I had to find out the LCD which is 12. since 6 goes into 12 twice I X 5 by 2 and got 4 10/12 + 3 8/12 which gave me 7 18/12 I divided that by 2 and got 7 9/6 and then divided that by 3 and got 7 3/2 which I thought was my answer but the that wasn't one of my choices. My choices are 1 1/6; 7 7/16; 8 1/2 and 8 2/3. What did I do wrong?

2 / 3 = 4 / 6
4 5 / 6 + 3 2 / 3 =
4 5 / 6 + 3 4 / 6 =
7 9 / 6 = 7 + 6 / 6 + 3 / 6 =
7 + 1 + 3 / 6 = 8 3 / 6 = 8 1 / 2
P.S.
3 / 6 = 1 / 2 
Simplify:
7 3/2 = 8 1/2
You could have made it simpler. The LCD is 6.
4 5/6 + 3 4/6 = 7 9/6 = 8 3/6 = 8 1/2 
4 5/6 } 5/6
+ 3 2/3 } 2 * 2 = 4
________  
7 3 * 2 = 6
Now add 5 + 4 9
  = 
6 6 6
Now as you see the number has become an improper fraction . So now you do this:
A: 9 9 3
7  =  = 9  6 = 3 = 8  =
6 6 6
1
8

8  is your answer because when you are
2
changing an improper fraction, you are actually simplifying . So when you were changing 3 , you were simplifying it to

6
It's simplliest form. And you get the 8 because when you were subtracting 9  6 you first count 6 which is one whole already, then you go 7 8 9 . Then you got 3 . So now you have to simplyfy it

6
to its simpliest form . So you divide it by 3 which then gives you 1 . Then

2
you just put the eight in the front of the 1/2 . That's your answer: 8 1/2 
my answer doesnt show good. I have to fix it.
