Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jackson spends 9 hours playing video games and 1/3 that much time studying. If Jackson's grade starts at 0 points and increases by 15 points for every hour he spends studying, what is his grade?

### Response:
 Kwanza tafuta jumla ya muda Jackson anatumia kusoma kwa kuzidisha muda anaotumia kucheza michezo na 1/3: masaa 9 * 1/3 = <<9*1/3=3>>masaa 3.
Kisha, mara namba ya masaa aliyotumia kusoma na ongezeko la alama kwa kila saa ili kupata alama ya Jackson: masaa 3 * alama 15/saa = <<3*15=45>>alama 45.
