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

### Instruction:
 Simon, Gerry, na Micky wanataka kuwa na mbio za mitumbwi midogo iliyotengenezwa kwa mikono. Mtumbwi wa Simon unahitaji vijiti 36, mtumbwi wa Gerry unahitaji theluthi mbili ya idadi ya vijiti ambavyo Simon anahitaji, na mtumbwi wa Micky unahitaji vijiti 9 zaidi ya jumla ya vijiti vya Simon na Gerry. Vijiti vingapi wanahitaji wavulana hao kukusanya jumla?



### Response:
 Mtumbwi wa Gerry unahitaji (36 * 2)/3 = <<36*2/3=24>>24 vijiti.
Mtumbwi wa Simon na Gerry unahitaji vijiti 36 + 24 = <<36+24=60>>60.
Mtumbwi wa Micky unahitaji vijiti 60 + 9 = <<60+9=69>>69.
Hivyo, wavulana wanahitaji kukusanya jumla ya vijiti 60 + 69 = <<60+69=129>>129.
