1 and 2 are correct.

4. If there are equal numbers of hamburgers and hot dogs, you have to have 3 packages of hot dogs for every 5 packages of hamburgers. If they are 12 and 20, respectively, then the buns are 15 and 15, respectively.

Are you sure you don't have a typo for the last question? If each number increased by 3, then the below would apply.

A 1 4 7
B 2 5 8
c 0 3 6 (9)
