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

### Instruction:
 Donna alikata pizza yake katika vipande 12 na akala nusu kwa chakula cha mchana. Alakula 1/3 ya pizza iliyosalia kwa chakula cha jioni. Vipande vingapi vimesalia kwa chakula cha mchana cha Donna kesho?


### Response:
 Pizza yake ina vipande 12 na alakula 12/2 = <<12/2=6>>6 vipande kwa chakula cha mchana.
Baada ya chakula chake cha kwanza, anabakiwa na vipande 12-6 = <<12-6=6>>6.
Alakula 1/3 ya pizza kwa chakula cha jioni, hivyo alakula 1/3*6 = <<1/3*6=2>>2 vipande.
Anabakiwa na vipande 6-2 = <<6-2=4>>4 kwa chakula cha mchana kesho.
