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

### Instruction:
 Lovely anagawanya keki yake ya kuzaliwa katika vipande 12 sawa. Chini ya robo ya keki ilikuliwa na wageni wake na iliyobaki ilihifadhiwa. Vipande vingapi vya keki vilihifadhiwa?


### Response:
 Kwa kuwa kulikuwa na vipande 12, na robo tu ilikuliwa, basi 12 * (1/4) = <<12*(1/4)=3>>3 vipande vya keki vilikuliwa na wageni wa Lovely.
Hivyo, vipande 12 - 3 = <<12-3=9>>9 vya keki vilihifadhiwa.
