2 and 1
11/3 and 12/3
2 1/2
1 1/2 + 1 1/2 = 3
1 1/2 + 1 1/2
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.

Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
Any two mixed numbers such that their whole number is 1 and the sum of the fractional parts is 1, eg: 1 1/4 + 1 3/4 1 1/3 + 1 2/3 1 3/7 + 1 4/7
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
Three mixed numbers that add up to ten are 3 1/2, 3 1/4, and 3 1/4. When you sum these, you get 3 1/2 + 3 1/4 + 3 1/4 = 10. Other combinations are also possible, such as 4 1/3, 3 1/3, and 2 1/3. The key is that their total must equal ten.
