So you should find the least common denominator first. 2.5 as a fraction is 2 1/2. The least common multiple between 2 and 3 is 6. So change the fractions so that the denominator is 6. So 2 3/6 and 1 4/6. The numbers are the same they just aren't simplified. Now you just have to subtract them. He has ALMOST one more pound of nectarines than apples. 2/3 is more than 1/2. So if you do the math he has 2/3 of a pound more nectarines.
