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

### Instruction:
 Amber anapika keki kwa ajili ya sherehe yake. Amewaalika marafiki 8 na kila mmoja atataka vipande viwili vya keki. Kila keki ina vipande 6. Ikiwa atapika keki 4, vipande vingapi vitabaki mwishoni ikiwa atakula tatu yeye mwenyewe?


### Response:
 Amber anahitaji vipande 16 vya keki kwa ajili ya marafiki zake.
Kila keki ina vipande 6, hivyo anahitaji 16 / 6 = <<16/6=2.667>>2.667 keki.
Atahitaji kupika keki 3, na kila keki itakuwa na vipande 6.
Vipande vilivyobaki vitakuwa 6 * 3 - 16 = <<6*3-16=6>>6 vipande.
