No. 5/8+5/8=10/8=1 1/4
First of all it is not reduced and secondly it is an improper fraction.
We normally call what you have said a common fraction.

I have no idea what the "sum" of a fraction means.
An improper fraction is when the numerator is a greater sum then the denominator. Example- 10/5. To change that into a proper fraction you divide the numerator by the denominator. Example - 2 1/5
The sum of three fractions with odd numerators can never equal one half because when you add three odd numbers together, the result is always an odd number. Since one half is a fraction with an even numerator, it is not possible to obtain it as the sum of three fractions with odd numerators. This can be proven mathematically by considering the properties of odd and even numbers in fraction addition.
The sum of a whole number and a fraction is called a mixed number.
If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.
