First add all the fractions together. Then, divide this sum by the total number of fractions that were in the set. This quotient is your average fraction.
If I had some fractions, I might. But since I don't, I won't.
All fractions are rational numbers because irrational numbers can't be expressed as fractions
Numerators
-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.

The same way that you calculate the average for any other numbers. Sum the fractions and divide the total by the number of fractions.
find the lowest common denominator
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.
Numerators
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.
