I promise I'm not cheating! I just need to know if these are correct. If it is cheating I didn't know. The rest I will figure out and do myself once I understand better.
1. 2 2/5 + 1/15 = 2 12/15 + 1/15 = 2 13/15
Is that correct?
2. 9 ½ - 5 7/12 = 9 6/12 – 5 7/12 = 8 18/12 – 5 7/12 = 3 11/12
Is that correct?
3. -4 7/8 x 2/3 = -4 14/24 = -4 7/12
Is that correct?
4. -3 1/5 divided by - 2/3 = -16/5 x -3/2 = -8/5 x -3/1 = -24/5 = -4 4/5
Is that correct?

1. No
2 2/5 = 2 6/15
2. Yes
3. No
You don't need a common denominator in a multiplication problem. But you do need to change the mixed fraction to an improper fraction.
-4 7/8 = -39/8
I'll post a response to question 4 in a few minutes.

#4, a negative divided by a negative is positive, so 4 4/5
