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

### Instruction:
The doctor told Barry to take vitamin D3 for 180 days to help protect him from infections. The pharmacy only sold vitamin D3 in bottles containing 60 capsules, with a daily serving size of 2 capsules.  How many bottles would Barry need to buy to have enough servings to last for 180 days?

### Response:
 Ikiwa kipimo cha huduma ni vidonge 2, chupa ya vitamini D3 yenye vidonge 60 itakuwa na huduma 60 / 2 = 30.
Kwa kutumia chupa zenye huduma 30, ili kudumu kwa siku 180, itahitaji chupa 180 / 30 = <<180/30=6>>6 za vitamini D3.
