You would start by finding the least common denominator of the two fractions. In this case it is 15. You would then convert your fractions from 2/5 to 6/15 by multiplying your numerator AND denominator by whatever number gets you to the the least common denominator you found previously. Do this again with 1/3 gets you 5/15. You then add 6/15 and 5/15 = 11/15. You know that Abena owns the rest so 15/15 - 11/15 = 4/15. Abena owns 4/15 of the estate
