find each sum or difference
1.
1/2 + 1/3
1. 1/6
2. 1/3
3. 2/3
4. 1/6
I got 2/3 because I added the 2 numerators and got 2 then I kept the LCM as the denominator so I got 2/3.
2. 3 1/5 + 6 1/2
1. 3 2/7
2. 3 7/10
3. 9 2/7
4. 9 7/10
I got number 3 because I added the two whole numbers and got a 9 then 1+1 which is 2 then 5+2 which is 7 so I got 9 2/7.
3. 5/8  2/8
1. 3/8
2. 7/8
3. 3/8
4. 7/8
I got number 4 because I subtracted the two numerators and got 7 and I knew it would be a positive not a negative cause a positive and a negative will end up as another positive and then I kept the denominators the same so that is how I got 7/8.
4. 9/10  2/5
1. 1 3/10
2. 1 1/10
3. 7/10
4. 5/10
it is number 2 because I added 9 and 2 and got 11 so I put one of the one's over and put it as a whole number then kept my LCM the same so I got 1 1/10.
5. 6 3/5  2 1/5
1. 8 2/5
2. 4 2/5
3. 4 2/5
4. 8 4/5
it is number 3 because I subtracted 6 from 2 and got a 4 so then I subtracted 3 from 1 and got 2 then I kept the LCM 5 the same so I got 4 2/5.

No, you are in serious trouble. You have several misconceptions about adding fractions.
