Answer:
All of them require multiplication
Explanation:
All of the questions say 'per person".
eg. 6: If it is 3 pieces of chicken per person, that means that each person gets 3 pieces of chicken. Since there are 7 people, that means that they, in total get 3 + 3 + 3 + 3 + 3 + 3 + 3 = 3 * 7 chicken.
