  2. q is 2/7 of the whole.Bonne réponse
  3. p is 5/2 times q.Bonne réponse
  4. p is 5/2 of the whole.
  5. q is 5/7 times p.

Explication

Together p and q represent 7 equal parts, giving shares of 5/7 and 2/7, while their pairwise quotient remains 5/2. Treating 5/2 as p's share is impossible because a proper part of this positive whole cannot exceed one.
