To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
2 mixed numbers can only be a whole when the 2 numerators add up to the 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.
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
Yes, if both the numbers have the same sign. But not if only one of them is negative.
