Quantity A: \((a+b+c)/5\)
Quantity B: \(1/5ab + c/5 = (1 + abc)/5ab\)

Since there is no restriction on the values of \(a, b, c,\) let us take some scenarios:

Let \(c = 0\): [Note: \(ab\) is not zero; \(c\) can be zero]
Quantity A: \((a+b)/5\)
Quantity B: \(1/5ab\)

If \(a = b\):
Quantity A: \(2a/5\)
Quantity B: \(1/5a^2\)

If \(a = 1\): Quantity A = 2/5 and Quantity B = 1/5
=> Quantity A is greater

If \(a = -1\): Quantity A = -2/5 and Quantity B = 1/5
=> Quantity B is greater

Thus, there is no relation
