I have no idea what the "sum" of a fraction means.

the sum the sum

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.

1/10 , 3/10 , 6/10 . Their sum is (1+3+6)/10 = 10/10 = 1

find the lowest common denominator

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.
