If p/q = p/(p+q), then p is what percent of q

Question

If p/q = p/(p+q), then p is what percent of q. Please Solve

Answer 1

multiply by q to get

p = p(q/(p+q))

divide by p

1 = q/(p+q)

multiply by p+q

p+q = q

subtract q from both sides

p = 0 = zero percent of q for any q. q = any real number except zero as it's in the denominator of the left side
