Well let's call the smaller of the numbers n
We know that n + (n + 2 4/8) = 7 2/8
In simpler form, 2n + 2 4/8 = 7 2/8
Subtract 2 4/8 from both sides to get
2n = 4 6/8
Divide both sides by 2 to isolate n, so
n = 2 3/8
To find the larger number, add 2 4/8 to the smaller number, getting 4 7/8

So the numbers are 2 3/8 and 4 7/8
