No.
yes 1.5 +.5 = 2 * * * * * No. 0.5 is NOT a mixed number. But 3.5 + (-1.5) = 2
The sum of two positive mixed numbers can not equal two because all positive mixed numbers are greater then one.no two can be, 1 1/2 and 1/2
When the sum of the negatives is an integer is when the sum is a whole number
No. Each mixed number is made of a whole number and a fraction. When you add them, you have the sum of two whole numbers and two fractions. Since each whole number must be at least ' 1 ', the sum of two whole numbers must be at least ' 2 ', and the two fractions will always make it more than ' 2 '.
No.
Only if you include negatives. The sum of 3 and 1/2 + -1 and 1/2 equals 2.
Yes
Zero can be expressed as the sum of any two opposite mixed number.
There is only one example where the sum of two mixed numbers can be equal to two. 1/1 + 1/1 All other combinations of mixed numbers will be greater than two.
Yes it can. Consider the numbers 31/2 and negative 11/2. Their sum is 2. So the question is misguided.
