I am happy to help... but <span>Please be more specific with your question.

This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300
In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2
So if I understand correctly, she had 7 1/8 pounds of birdseed and used 3/8 pound.
Convert the 7 1/8 to an improper fraction [(8*7)+1]/8 =57/8
57/8 - 3/8 = 54/8, which is 6 6/8 which reduces to 6 3/4 pounds left
If she had 7 pounds of birdseed and used 3/8 pounds, you need to find a common denominator to subtract if you can't do it in your head. 8 would be the common denominator, so:
56/8 - 3/8 = 53/8, which is 6 5/8 pounds left
