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

### Instruction:
 Kuna meza 15 katika cafeteria ya shule. Kila meza inaweza kuketi watu 10. Kawaida, ni kiti 1/10 tu kinachobaki bila kuketiwa. Kiti ngapi kawaida kinachukuliwa?


### Response:
 Kuna meza 15 zenye viti 10 kila moja katika cafeteria ya shule.
Hii inamaanisha kuwa viti 15*10 = <<15*10=150>>150 vipo.
Kawaida, 1/10 ya viti vinabaki tupu, hivyo viti 150*(1/10) = <<150*(1/10)=15>>15 vinabaki tupu.
Hii inamaanisha kuwa viti 150 - 15 = <<150-15=135>>135 kawaida vinachukuliwa.
