Package #1 = 5/8
Package #2 = 2/3

So for both fractions (5/8 and 2/3), we need to have a common denominator. In this case, the common factor of 8 and 3 is 24.

1. Multiply 5/8 by 3


(5*3)/(8*3) = (15)/(24)

2. Multiply 2/3 by 8


(2*8)/(3*8) = (16)/(24)

3. Simplify


(15)/(24) + (16)/(24) = (31)/(24)


(31)/(24) = 1(7)/(24)

The total weight of the two packages is 1 and 7/24

Package #1 = 15/24
Package #2 = 16/24

Subtract:

(16)/(24) - (15)/(24) = (1)/(24)

The second package is 1/24 heavier than the first package.
