$3$ granola bars, $4$ raisins.

#### Explanation:

To do this type of questions, we need to find the lowest common multiples as it will allow the same amount of raisins and granola bars, where we can they work out the amount of packets.

Multiples of $9$

$9 , 18 , 27 , 36 , 45 , 54 , 63 , 72 , 81 , 90 , 99 , 108. . .$

Multiples of $12$

$12 , 24 , 36 , 48 , 60 , 72 , 84 , 96 , 108$

As you can see, $36$ is the lowest number that each have.

Dividing $36$ by our original values gives us the amount of packets for raisins and granola bars.

$\frac{36}{12} = 3$ packets of granola bars.

$\frac{36}{9} = 4$ packets of raisins.

In regards to how many years packages, you have not stated how many packets, or how much snack bags needed he gets in a year or similar, we need more information to answer this part of the question. If you mean this is a years package, then it is simply $3$ packs of granola bars, and $4$ packs of raisins.
