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.
