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.

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